Ianto shuts the door behind himself as he steps into the door, shucking his bag off his shoulder as he does and doing his best not to stare at the other man's arm. He'll see it up close and personal soon enough.

"Yeah," he replies, moving closer to kneel where he'd done before and setting the bag down in front of him, starting to dig through it once he's done so. "I found a few things I thought you might be able to try out, if you're interested. They told me you were safe to mix and match, for the most part. Within reason." He holds up the little extra sack he'd been carrying. "And some ice, of course. For once we're done." He probably could have left that to fetch later, but it should keep for the most part and he can just refresh it if it doesn't.

Plucking out a little vial, he holds it up to the light, squinting for a moment before displaying it to John himself. "Here. From what they told me about this, it sounds like it should do the trick. Though you might want to start out light, in case it hits you hard to start."

He glances up at John's arm, pressing his lips tightly together as he does, before continuing on to begin, "How's..." He trails off again before even finishing the question. Does he really even need to ask? He's got a feeling he knows just by looking.
