Would she not show in a lively form but rather a flashback? Or will she be all Real and non-ghostly.? :D
What i Want:
AFter Esther turns her children into vampires by using tatias blood as an ingredient maybe an original feeds on her and turns her. But maybe since they had just become vammpire they didnt know she'd come back to life and she could have possibly ran off. I Hope she is still alive and a vamp and pulls a "Katherine" by impersonating either kat or elena. Although the Salvatores may notice its not elena, they also should be able to tell that its not Kat either. Leading them to the idea that another doppleganger lives. This is where the Original triangle meets and gets involved. But if tatia was turned by an original it was most likely by elijah or klaus. But then wouldnt that make her sired to them if she was really "In-love" with them. If she's sired theres no doubt that she wouldnt seach for them, and if she was looking for them, she surely wouldve found them at an earlier point in the 1000 years they've been vamps. Then feelings would stir up, either hatred, or love.
Another thing to take notice on: The salvatore brothers were turned by katherine, whom they had a LOT of feelings for. In order to sire to a vampire when you are turned into a vamp is if you have feelings for the vampire whos turning you. Although katherine may or may not have had feelings for the brothers , she didnt have to in order for them to sire. Why is it that they arent sired? Is it because they lost their feelings for her over time? I don't think thats possible because elena has sired that one girl in New Orleans and she still had feelings for him when he returned decades later. In epiode 4x07 , Caroline says that it Is exceptionally rare, a one-in-a-million occurrence. But can we take what this Year long vampire said seriously? Does she actually know what she's talking about? :D Idk, let me know your opinions on these two topics. Thanks.
