You got sent back. I got sent back. We've all been sent back. Cora was dying when she first came here. Which means, I hadn't healed her yet. Which I have done now. I healed her and we left Beacon Hills. I'm sure this is all this is. She'll come back to us.
Do you believe she loves you? I mean, I know for a fact that she does but you do believe it right? Because it takes a hell of a lot more than magic to make someone forget the sort of love she has for you. You are the first person she's let take care of her since the fire. See her vulnerable. The human heart is a strong thing but a werewolf's heart is pretty damn strong too. Besides, if she came back, you'd fight for her. You know you will.
We're going to figure this out, Kid. We're going to figure out what's going on and she is going to come back. I am not going to let you go crazy.
