[He takes one stumbling step backward and huffs, reaching to pull Kaiba with him. He doesn't want to give up the proximity. Which will make getting Seto into the bathroom difficult, but he'll deal with that hurdle when he comes to it.]

You know exactly what I mean, Kaiba. You're just trying to get me to say it to embarrass me.

[He's already embarrassed! This much embarrassment should be satisfactory!!]

I'm sure you'd prefer company right now- so would I, actually, but I have vested interest in maintaining this current, tolerable level of hostility.

[Seto doesn't want to kill him; he's even willing to let Pegasus paint for him, and he has just enough cognisance and self-control to want to keep it that way.]
