"I was joking," Derek confirms, though he doesn't let go of Bitty's hand, and tells himself it's because it's so cold. They walk in silence for awhile, and Derek does feel a bit better. He squeezes Bitty's hand and opens his mouth and closes it a few times before finally getting the words out.

"It means a lot that you want to be pack," Derek says quietly. "Because you're the only one who knows all the mistakes that I made the first time."

They don't talk about it much, how Bitty knows so, so much about him. Sometimes it's too much, but sometimes Derek is grateful for it. He feels vaguely unburdened, having someone else who knows everything.
