[Sora's life?! It does occur to Riku that Bakura can potentially harm Sora's body while he is in it, or hurt Riku and Riku won't be able to do much against him, so he doesn't have much of a reason to lie to him.]
I'm not a popsicle! [God! He turns and tackles Sora onto the bed, pinning him down again, frustration tightening in his chest. This is practically mortifying, and he knows he'll have to tell Sora about it later.]
You're disgusting. After you tell me how to find you, get out. Or you'll suffer something much worse. [It's a threat he's not sure will hold water, but he knows there's a few options for getting Bakura out of Sora's body, hopefully.]
