I’m sorry I kinda had to
Oh god, that's just. Like Cora not really being Derek's sister and being a part of the Alpha Pack makes a lot more sense than what the show actually gave us, but that is honestly just a heartbreaking thought. Like, Derek in s1 & s2 with no family left except for Peter is awful, but imagining him thinking that he got someone back only for him to find out none of the memories are even real is just. </3 I can't even think about the look on his face when Stiles figures it out and tells him.
