[Under lighter circumstances Hange may have taken this opportunity to mess with his hair a little, change the parting and try out a new style or something like that, but the mood isn't right for it so they simple keep to his usual style, evening out the parting and combing through the strands to make sure it's free of any knots.]

There. You look cool!

[Even though if Levi were to look in the mirror he'd see that he looks exactly the same as he normally does... spoiler, Levi, you always look cool.]

[The comb is set aside and once again there are a couple seconds of silence... its common to see Levi annoyed, or pissed off, or sarcastic, but it isn't often that they have had to deal with him looking genuinely kind of sad...]

[Hange decides to step forward and pull him into a light hug, one he could easily wriggle out of if he wanted to.]

It's the easiest way to replenish that magical energy you know, after being away from everyone for so many days.

[Yes, the hug simply has a practical use. It has nothing to do with their best friend looking so gloomy and wanting to cheer him up, and wanting to deal with that ache it creates in Hange's chest..]
