Vicki would have quickly been sorted into Slytherin. Her actions before her death in season one were very self-serving. Vicki wasn’t too worried about hurting people to get what she wanted until she was stuck on the Other Side, watching everyone she loved.

Meredith was brilliant, which isn’t just a Ravenclaw trait, but she was also creative in the ways to help her patients. And yes, I’m calling cheating by using vampire blood creative. That’s why she’d be in Ravenclaw.

Lily could've been sorted into Slytherin because of her actions. However, when looking at her motivations, they weren’t self-serving; it was to protect her “family” of heretics. Everything she did was to protect them, even when they came up against her own sons.

Alright, let’s talk about Tyler Lockwood. While I’m giving him a slight break because his werewolf side gives him a short temper, he has most of the other Gryffindor traits. He’s brave, reckless, and determined beyond belief.

Katherine was immediately sorted into Slytherin. She was always doing whatever she could to save her own skin – even killing herself to become a vampire and escape Klaus. Katherine even body-snatched Elena to get more time with her daughter and Stefan.
