and i feel that she might in the far future but i think for now she wont and that she doesn't even want to be one right now. And i dont think they will ever be each others 最喜爱的 person but i think that they might get civil with each other and put their differences aside and work together cause it seems like they have no other choice but to do that :)
Elena does turn into a vampire, and i honsetly dont think Kathrine and Elena will ever get along, becaus Kathrine loves stefan, stefan loves Elena and Elena loves him back, so she wouldnt like someone coming around stealing her boyfiend. Kathrine also has a charecter that is like she will only do whta she wants, and they are very diffrent and thus they wont get along...
