I think we can all agree this isn’t Terezi at all. Terezi doesn’t stutter or stall for time. Terezi isn’t hesitant. Terezi doesn’t accept Vriska’s words just like that.
If this Terezi hasn’t been through three years of a bad relationship with Gamzee, then she’s gone through three years of something different that’s left her a bit too compliant to my liking. :/
