Ianto noticed the brief look that Sulu shot at the amulet, and was a bit self-conscious of the object around his neck, really. It was true, he was hesitating to take it off, but. With good reason. For all that he didn't feel very well, he was still grateful to be alive, and none of them really knew for sure if the amulet was merely a way to help channel whatever sort of magic that was used to bring him back, or whether it was the only thing keeping him alive and if he took it off, they might be right back where they started. He usually hid the thing under his shirt, not wanting to show it off, it making him just as uncomfortable as it made Sulu in that moment, but. With no shirt on, hiding it was rather hard.

He smiled gently at Sulu kissing the back of his hand, before trying to process what it was that Sulu was asking. "How do I want to...?" he asked, before realizing what Sulu meant. He blushed, again. "Oh. Well. I... I guess we're probably going to have to, ehm. Y'know. Sit together. If. If that's alright with you, that is." Ianto didn't want to mention it out loud, but. It wouldn't be a bad idea for Sulu to stick close to him. Especially if he did start to fall asleep in the tub.
