Sulu honestly didn't mind taking care of Ianto, not when he was this sick. Really, even when perfectly healthy, Sulu wouldn't mind doing these sorts of things for the other man. He wasn't prone to doting on people, so when he met someone he really did want to do things for, it sometimes was a little strange. Still, he threw himself into it from the beginning of this whole debacle, and he would continue to dote relentlessly until Ianto really didn't need it any more.

"No," he said in response to Jack's question, grinning. "As far as I've ever known, I've got no allergies whatsoever. You're good to go, captain." At least, hopefully Sulu didn't end up having some kind of allergic reaction to something Jack was using. That really would be just great.
