[It was a difficult battle between Shiro and Keith to determine who is the worst cook, but alas, Shiro wins out. And the reason he's selected is soon revealed as the... pie(?) dough he's working on is, uh. green.]
[In his very, very limited defense, he knows that he's fucked up and that the pie dough being green is not a good thing. He's eyeing the trash can with no small amount of shame.]
I mean, it's bad to waste food, though, isn't it...? [But also who would want to eat this???]
