He wrote a new story every day, and reminded me to always find the light.||”|

He meets a mysterious woman, and quickly begins liking her, explaining to Kaleb that he feels as though she is "the one".

In This Year Will Be Different, Kaleb overhears Lizzie announce that it is her year to embrace opportunities and sees this as MG's chance to ask Lizzie out on a date.

Not long after, MG practices with Kaleb what he is going to say when he reveals his feelings to Lizzie. After multiple practices, he finally feels ready, but when he goes to tell Lizzie she shuts him down, revealing that she has met someone she feels she will get along with. This breaks MG's heart, but he tells Lizzie that he is there for her as a friend. In You Remind Me of Someone I Used to Know, MG invites a reluctant Lizzie to the annual charity football game. He tells her that he will help her find out what species Sebastian is if she attends the game; she is at first reluctant but eventually agrees. At the game, he approaches her and uses his enhance-speed to look read the books she is reading, but cannot give her a definite answer on what species he could be. He later pleads with Lizzie to return to the field when Ethan takes up post as Timberwolf-quarterback. She initially refuses but agrees when she notices Sebastian is watching. MG notices Lizzie leave the game to follow Sebastian, and follows her. He watches as she kisses Sebastian in the basement of the Salvatore School, however, he is unable to perceive Sebastian, and to him it looks as though she is kissing the air. In Since When Do You Speak Japanese?, MG asks Wade to borrow some recording equipment from the school in an attempt to show Lizzie that Sebastian is a figment of her imagination. Wade hands him a video recorder and tells him that all of the other equipment is booked. MG turns on the recorder to find that the tape already has a recording, which Wade tells him to overwrite. Unbeknownst to him, the tape is actually a message from Malachai Parker, sent to Bonnie Bennett in I'm Thinking Of You All The While. Nevertheless, MG overwrites the tape when he watches from afar as Lizzie has a picnic with Sebastian by the lake, although to him, it seems as though Lizzie is talking to herself. He shows Lizzie the tape, which breaks her heart but leads her to telling MG that the two are no longer friends and he doesn't exist to her. Upset by the events, MG hands Wade back the recorder, citing creative differences. However when he is about to leave the lounge, he is approached by Sebastian — who is revealed to be real — who asks what he told Lizzie as he can no longer reach her. Wade asks MG who he is talking to, further revealing that the only person able to see Sebastian is the person he is talking to. In Screw Endgame, MG struggles being the only one able to see Sebastian. He is eventually able to bring Kaleb around to believing in Sebastian's existence, and Kaleb has him question what he wants. Sebastian reveals that he wants the two for them to find his body and awaken him. The two eventually find his body, but are unsure of whether to resurrect him or not. MG begins to lean on the side of awakening him when Sebastian promises to leave town and therefore, open up Lizzie to a relationship with MG. Nevertheless, they consult Alaric, who, much to MG's dismay, suggests that they leave Sebastian desiccated wherever he may be as they do not know his history. At the end of the day, MG uses an enchanted mirror to speak with Kym. She notices a man standing in the background and points him out to MG, who turns and notices it is Sebastian in the flesh. In That's Nothing I Had to Remember, MG is a part of the plan to capture Sebastian after he escapes. He, Kaleb and Kym are successfully able to capture and chain Sebastian up, where they later question him on the croatoan terrorizing the town. Sebastian is at first reluctant to help, but divulges key information to MG who relays it to Lizzie. MG does, however in this time, get into an argument with Sebastian after Sebastian calls him out over a remark he makes about Cassandra, Sebastian's ex-lover. When MG and Sebastian — as well as all of the world — get their memories of Hope (and their histories) back, Sebastian tells MG all about his past, including how to kill the croatoan. Sebastian hands MG his necklace, allowing him to use his vampiric speed to deliver it to Hope. At the end of the episode, Lizzie and Josie talk about Landon, when MG and Sebastian enter the room. Lizzie at first believes herself to be relapsing when she sees Sebastian, however, Josie reveals that she too can see him. This leads to MG revealing that Sebastian is actually real and the two have a lot to talk about.
In I Couldn't Have Done This Without You, MG and Lizzie hang out and read comics together. Lizzie expresses her concerns about her current sexual activities with Sebastian over fears of obsession — she tells MG that the two cannot stop having sex. Lizzie jokes that she is trying to avoid Sebastian until he gets kicked out of the school.
Later, MG expresses his distaste towards Sebastian with Alyssa Chang. Alyssa convinces him that they can ensure Sebastian fails the assessments and is thrown out of the school. With this, she cuts her hand purposefully, however, MG is the only one affected by the blood and is restrained by Sebastian in return.
In What Cupid Problem?, MG expresses his romantic feeling for Kym to Kaleb, who is shocked and against the idea. Kaleb pretends to be supportive of the situation, however, and he gives MG advice on how to impress Kym. Eventually, it is revealed that Kaleb lied, telling MG things that Kym is either allergic to or completely against.
Instead, MG uses the perfect date he had planned for Kym with Alyssa, in an attempt to seduce the location of the ascendant from her. His date does not go as planned, however, and MG asks Alyssa to reveal the ascendant's location. She eventually shows him the ascendant, but breaks it before his eyes.
In There's A Place Where The Lost Things Go, MG is a part of Emma's simulation and plays a detective working under Rupert Vardemus. In the simulation, MG is looking for Vardemus, and attends Landon's, the bar owned by Hope. Hope initially dismisses him, but MG warns her that he knows her liquor license has expired — a finable offense. MG goes behind the stage to speak with Emma, but finds she has been murdered, with Vardemus looking at her body, all signs point to him being the murderer.
MG takes Vardemus in for questioning, however Vardemus is adamant that his name is Sherlock Holmes, despite MG's reluctance to accept his employer's absurd comments. MG accuses Vardemus of the murder, citing that his fingerprints were found on the victim, however Vardemus remarks that he was wearing gloves, therefore this is impossible.
When MG arrives at Landon's to speak with Hope, he finds that someone had ordered champagne for Lizzie, therefore she — not Emma — was the target of the murder. MG tries to tell Lizzie about the situation but she faints, and MG promises her that Vardemus will get to the bottom of the murder.
Later, after accusing Josie of the murder, MG goes to talk with Lizzie again. After a while, Lizzie becomes self-aware, followed by MG. The two of them ares surprised that they have not woken, however after being attacked, MG wakes and it becomes clear that Lizzie and Josie are still stuck within the simulation.
In Life Was So Much Easier When I Only Cared About Myself, when Josie arranges the Merge prematurely, Lizzie flees the Salvatore School in fear of losing to Josie. MG follows Lizzie and tells her that he will run away with her, but believes that, deep down, she can win the Merge if she tries. Lizzie realizes that MG was never going to run away with her, but the whole ordeal was a ploy to convince her to come back to the school.
In Facing Darkness is Kinda My Thing, MG is tasked with planning Lizzie's "fake funeral", however is worried that Lizzie being involved with the planning will more than likely give away the fact that she is still alive. MG prepares a eulogy for Lizzie, and is upset when Lizzie demands that she herself will give the eulogy.After Lizzie's eulogy goes badly, she prepares to reveal herself to the school, however is surprised to find MG delivering his eulogy for her. Lizzie is moved by the eulogy in which MG explains that Lizzie tried to change numerous times, but the school would not allow her. Lizzie is moved by the eulogy and — given MG is a vampire and will never be at his funeral — writes and performs a eulogy for MG down by the river.
MG is described as being a "popular, kick-ass and brilliant nerd."
"MG is a kid who spent his whole life putting on a show. He had to be smart, mannered, and put together all the time in order to not embarrass his parents, especially his father who was always in the public eye. This meant suppressing his natural personality in order to be the perfect son -someone as charming and charismatic as his father. Of course, practice makes perfect and MG has had lots of it. He's crafted the persona of the perfect guy so much that peers and potential lovers alike are drawn to him... but never the one he wants: in this case, Lizzie Saltzman. MG feels like a failure because his worth has always been tied to others' approval. Unfortunately from his experience, approval/acceptance is the only way to achieve happiness."
He is a young vampire who wears the standard school uniform, while he wears dark or light-colored clothing when class isn't in session. He has dark brown eyes and dark brown hair that is usually styled in an afro, but is only rarely pulled in a bun.
Powers and Abilities
MG possesses all the standard powers and abilities of a non-Original vampire. Furthermore, he has been discovered to be a ripper, a vampire driven by blood and obsession. He is prone to losing control when feeding on human, but more particularly when seeing or to the scent of human blood.
MG has the typical weaknesses of a non-Original vampire.
At first, MG was not good friends with Kaleb and often competed with him at their school. However, due to spending time with Kaleb, MG grew closer with him. The supernatural events happening at their school in the first season of, "Legacies," forced them to ally with each other. This bonds them together a bit. However, after MG loses touch with his biological family due to his vampirism, Kaleb promised to be there for MG and he told MG that he is his family now. They are currently close friends and allies.
MG seems to be good friends and allies with Penelope. She is often trying to help him win over Lizzie despite telling him to stop it. However, MG doesn't know when to quit, which frustrates Penelope being she has a personal bad history with Lizzie and cares about MG as a friend. MG and Penelope have even made out once, but this was when Penelope attempted to convince MG to drink human blood. Despite this momentary lapse of temptation, MG and Penelope have remained friends. It also seems they grew closer in Mombie Dearest after saving Josie from zombies.
MG and Lizzie are close friends, have known each other for a while. They both attend the Salvatore Boarding School, however, MG usually only garners attention from Lizzie when she needs something from him. However, this fact doesn't stop MG from having romantic feelings for Lizzie. For now, Lizzie doesn't return the feelings MG holds for her, but it frustrates her whenever MG flirts with other girls, whether they are human or supernatural. Their friendship was rocky when MG made out with Lizzie's twin sister's ex-girlfriend, but they have since reached an understanding on the matter. Their biggest fallout occurred when Lizzie began seeing a mysterious vampire named Sebastian. MG followed her one night of curiosity for who Sebastian was, and witnessed her seemingly kissing the air. He feared she had a mental break and confronted her with a video of her talking to what seemed to be herself. Unbeknownst to MG or Lizzie at the time, Sebastian was real but desiccated and reached out psychically to Lizzie. MG later freed Sebastian and told her the truth, which caused a large rift between them. She struggled to forgive him for setting her back in her mental health journey. She eventually did forgive him and the incident allowed them to grow closer as friends. Before Lizzie entered the merge she siphoned magic from MG with his permission. She did this by kissing him but stated the kiss was for him and not her - just in case she didn't survive. In all actuality, Lizzie faked her death after losing the merge, and MG was relieved that she was alive. During her memorial to perpetuate the idea of her having died, MG was the only person who stepped up and gave a supportive eulogy for Lizzie. He even called out his fellow students for their inability to allow Lizzie to change or accept that she has changed. Afterward, when everything was resolved, Lizzie returned the sentiment by giving MG a moving eulogy about how great of a guy he is. They are currently close friends and allies when defending the school.
