[ Well, he did live (somehow, someplace, technically), and now he has to deal with the consequences. Didn't plan for that, now did he? Perhaps he should worry less about being perceived free and more about being a person, not that he hasn't been making huge strides in that so far. ]

[ (Levi does not have a profile. Hange does, however, and as it turns out, they share quite a lot of things between them...) ]

[ It is perhaps (very tangentially) about Reiner, but more than that, it's about what he represents for Eren. It's... a coming of age of sorts, or a realization of it, or maybe Levi deciding that he's proven he's enough of a person now to be regarded as such. As far as he's concerned, there are some important milestones to becoming a man an adult, and clearly being able to dress the part was one of them. ]

[ Nobody had been there for him at that moment -- the closest he got was probably Kenny letting him wear his hat once as a child or something -- and damn him if he's not going to be there for Eren when he has nobody else and they literally live under the same roof. No, that just won't do. ]

[ The mutual staring continues. ]

That you need, sure. But we're not struggling to survive right now, Eren. We should take advantage of that while it lasts.

[ Because it's never a given that it will. Hasn't he learned anything from the lessons Levi did try to impart on them? ]

[ His expression becomes flatter, somehow. ]

Do you have a single shirt with buttons?

[ He sure hasn't seen one! ]
