|“||And you? Fated to watch from the shadows? The noble martyr? Fate does not dictate my heart, Elijah. I was fated to throw myself on a pyre after my husband died in battle, but I did not. I chose to live. And, I chose to give my heart once more. To someone strong, protective, fierce, and yet noble, and gentle. I choose you, Elijah.||”|
Although not much is known about their early relationship or how their relationship developed, Tatia and Elijah lived in the same village, later to be known as Mystic Falls, in the 10th century. Tatia was originally married with a child, however some time after the death of her husband in battle, she formed a relationship with Elijah.
During a party, Tatia is first seen dancing around a fire while the village celebrates the Samhain, with Elijah watching her in the distance from a pig pen. Tatia takes away her mask to smile at Elijah, although Klaus, dancing beside her, swings her arm around and begins to kiss her. Elijah's smile drops as he turns away and begins to feed the pigs. Tatia soon breaks the kiss and stops dancing with Klaus as she realizes Elijah is no longer watching her, and she takes off her mask to search for him.
Finding him beside the pig pen, she playfully quizzes if he is to save Loki the pig from his fate. Smirking, Elijah responds Loki's fate is to become food, while admitting that her fate is to love another. She turns the tables and asks if his fate is to watch from the shadows, "the noble martyr", before explaining she does not let fate dictate her heart. After her husband died, she was expected to throw herself on the pyre, although she chose to live and open her heart again, to someone "strong, protective, fierce, yet noble and gentle" before announcing that she chooses Elijah. Elijah is elated and moves in to kiss her, she backs away laughing at their unromantic spot. He smiles and kisses her anyway. He breaks the kiss and tells her they should let Loki the pig free as fates change, before kissing her again.
The morning after Klaus first transformation into a werewolf, Tatia comes across the torn apart bodies of some of the villagers that Klaus had killed. Tatia runs after seeing Elijah as she's now afraid of him, telling him that she didn't think the blood she gave his mother would turn him into a monster. While running Tatia falls down and cuts her hand drawing blood. Elijah new to being a vampire and doesn't have the control to resist the scent of Tatia's blood. He begs her to run but before she can he attacks her and begins feeding on her as she screams.
Elijah later brings her lifeless body to his mother hoping that she can help Tatia but she's already dead. He's shocked and horrified that he killed her. So Esther takes away the memory of him killing Tatia and taking the blame herself and she tells him to clean himself up. Through the centuries due to his mother taking away his memory, he believed he had just compelled Tatia to forget what she saw.
