[Even though he's been lucky enough to have never broken anything, Kai's well aware that having a busted hand most likely hurts like hell. He's as gentle as he can be while he examines it, not just because it's Ryou's hand he's dealing with. He's not a jerk all the time.]

Trained or not, if I manage to completely heal it you'll have to pay me. Can't let my awesome skills go unrewarded, right?

[Joking while he deals with something serious, check. Holding Bakura's hand carefully between both of his, Kai lets out a soft breath, casting Cura. The warmth of the green light surprises him for once; it's stronger than what he used on Karasu, but he's pretty sure he's not overdoing things. Once the light sinks into Bakura's skin and fades, he releases his hand, sitting back to rub his forehead. Ouch.]

Don't screw anything else up for a day or two, huh?

[He has no idea how well that worked, and he's not going to admit it.]
