I think Stiles gets straight A’s. The behavioral issues line is the key there, and it’s not the kind of phrasing a parent usually uses unless they have a child with behavioral/learning issues. It’s a cool, telling moment. I know there’s some uncertainty as to whether or not Stiles is actually meant to have ADHD, but I think the hints are there—especially in Sheriff’s interactions with him. It makes me think that Sheriff believed his wife to have a good handle on Stiles’ issues, that she knew what she was doing, and that he doesn’t. He’s struggling sometimes; he wants to be the parent he thinks she would have been. Conclusion: Stilinskis!
Also I love the repetition because I think they’re both very routine-based, even in the conversations they get into—the familiarity and comfort in the same play-arguments. Snarking is a sign of affection in the Stilinski family.
