Considering recently it was more likely to find Sam in a bottle than with his head stuck in a book, Derek would take the book immersion over the alcohol, with the way things changed so suddenly around here, it seemed like a much better distraction.
Definitely better health wise.
"I don't know, I think you're well on your way to courting them." A petty joke, but one that was probably going to have a relatively long life here too. "There's only so long I can spend around hormonal teenagers." Which wasn't entirely a lie, eventually the kids really did get to Derek and he needed a breather. At least when Sam was sober he was far less child-like than Clint.
