Sulu let his smile grow into a real, honest one, though it was by no means very big; he'd sort of dreaded Ianto's response, because all he wanted was for things to get better, for Ianto to get better, and if he was okay with taking on the stairs, it was obviously not as bad as his subconscious had been making it seem.

"I was only offering because I wouldn't normally," Sulu said, stroking the top of Ianto's hand with his thumb once more before letting go, sliding off his side of the bed. "So maybe you should take advantage of my great bedside manner while you can, because I'm not going to offer when you're better. Except on your birthday, maybe." He moved easily to Ianto's side of the bed, holding out a hand to help him out of bed - and also just because it was nice to be able to have some kind of physical connection with Ianto, even if he was a little cool to the touch.
