Scarred's just mad because he's bald at the moment. Unless his hair grew back already.
Nah, he just gets irrationally jealous whenever somebody posts a photo in which they're not pulling a silly face. He think to himself "How the hell do they
do that?" and he resolves that next time, next time for sure, he'll be straight-faced when somebody takes his photo, but every time he fails. Every time he fails, and what's more he knows he will, and sometimes the other people in his house can't sleep for the soft, ceaseless sobbing that comes from his bedroom very late at night.
Or so I imagine.
