Stiles and Lydia in “Unfinished Business”

Stiles

Okay, then what are we doing here if you've already had your repressed memory?

Lydia

[frustrated] It wasn't the right memory. I remembered my grandmother in Eichen House. There was nothing to do with surgery, nothing to do with the Dread Doctors. So, if I've read the book, why don't I have the full memory of my experience with them?

Stiles

...I'm not supposed to know that, am I?

Lydia

No, something... [She suddenly gets an idea] ...happened during the surgery. But now... I think that maybe it has more to do with me being a banshee. It's not my memory, Stiles. :Stiles: It's someone else's.
