Bro doesn't know what to do with you. He never has. He feels like raising you has all just been a big blur, from when he found you to now. He's been a functioning alcoholic since before he adopted you, and that's never changed, but he's always at least tried to give you someone to look up to; something to strive towards. Maybe he was misguided, but he thought that if he was tough on you, it'd teach you to be strong, it'd make you into a capable adult, but now you're here. Crying in your bedroom. Unaware that he's standing in the doorway watching you.
"... Kid?" Bro mumbles, sounding uncharacteristically awkward and uncomfortable. He's so unsure of what to do when you're so emotional. Bro's father just taught him to keep those sorts of emotions inside. He has a feeling that's not going to work here.
