The five times Derek called the Sheriff "Dad" on accident and the first time he did it on purpose.

Clary has never been any good at putting things back together. When they were in middle school and she accidentally knocked over Simon’s Lego Millennium Falcon, he’d already known to say it was fine repeatedly and usher her out the door instead of accepting her offer to help him rebuild it; if he’d let her try, the wings would have ended up upside down and there suddenly wouldn't have been space for the engine. Her heart is in the right place, usually, but it doesn't often translate to her hands. So when he hears through the shadow world gossip mill that Alec's parabatai rune disappeared briefly, it doesn't take more than one look at Jace’s face to know that she’s been fucking around with the threads of fate again. And, well. She's never been that great at sewing, either.

And now he’s just… how the fuck is he even supposed to talk to Tyrion in his life without blurting hey, you know what, I’ve just discussed a few things with my therapist and guess what, I let her ruin your life, too, and I didn’t understand how much, and I didn’t even hear you out when you tried to tell me and you had half my fucking years, will you ever forgive me for that? He has no fucking clue. He has no bloody fucking clue, and fine, that is why he’s pretty much unable to think of anything else, but it still doesn’t mean he had any right to be a fucking arse to others.

“Very well. I’m going to tell you straight up — when you told me you hadn’t remembered that episode at all, it was a red flag. Given everything else you’ve said up to this point and how you reacted to recalling it and what you’ve said about your general coping mechanisms —” “Coping mechanisms?” “You might not know it was that, but you’ve used a lot of them. And this is where I tell you that repression or suppression of traumatic memories is very common, when discussing child abuse victims. Especially male ones.” He doesn’t know why his first instinct is denying it. It’s fucking ridiculous. He went to a guy who’s a fucking authority on the subject because deep down he knew that could be the issue, if he even thinks about that one memory he wants to throw up, since he remembered that he hasn’t been able to walk near dogs without wanting to jump on the other side of the road, it’s been two months and he’s gained a new awareness of how unhealthy his entire life was until he broke it off with her — And still, his first instinct is telling him, it can’t be?
