(He takes his hand and turns it over so he can look at the palm,)

Your hands are dirty.

(He pops the last candy into his mouth and reaches out with it. He rubs at Aki's hand,)

You should take care of yourself first, Aki-kun. Then, you can take care of others.(Of course, his own hands are dirty so there's only so much he can really do right now,) When we're both like this, we can't do much.

(He's making a point, really.)
