He's confused about why this thing is talking to him until he realizes she's probably talking about the sack of shitbeloved little brother he's half-carrying.] [he wishes he could just kill her on the spot and be done with it. but with none of the necessary drugs in his system, it'd be more trouble that it's worth. that and it'd call so much unwanted attention.] [what absolute pests these humans were.]
[Putting the churning animosity aside for now, Birdman dons a softer face.]
This one here's hurt. He's my little brother.
[Eyeing that concern in her face, he glances briefly at Cain, then back at Yuuki.]
Do you know him?
[ooc note: If it turns out that Robin helps Cain into the actual hospital, we can always backdate this to right before Robin and Birdman meet if that's okay with you ;3;]
