[This is... well, the opposite of what she wanted to happen. She had wanted this to be a good thing. She had wanted this to be good news and for him to be happy for her and instead everything that they had talked about that whole morning felt like it didn't even matter. All the jokes and laughter and not so light teasing -- maybe she should have told him sooner. She hadn't really told anyone and she knows that it's because Stiles knew and Isaac didn't.

At least, that's what she thinks it is.]

I'm sorry, Isaac. [The apology falls out of her mouth nearly as quickly as she can think to say it. Her arms fold over her chest, pulling herself inward and trying not to focus on his body language in relation to hers.] Everything with the sleep walking and the -- the things I thought I did. I decided to at least try whatever I could to not be so weak, so that maybe whoever did that... so they wouldn't try it again.

[She's not sure she wants to bring up that she decided after he died. That she'd been left alone with the thought that Isaac had died and she hadn't been there... not that she wanted to be the one to -- no, that's not it at all, but she was tired of being shuffled aside because people were worried she wasn't strong enough. Isaac had let her fight with him before -- she thought he'd understand.]

I should've told you what I was going to do. [In a way, not any way that she might realize it in the moment, but Isaac had become a surrogate alpha to Erica. Not that she could understand that concept, especially not with how things with her and Derek always went, but the big brother part of Isaac was something she relied on and now, now that she can see how she's let him down the guilt weighs on her.]
