Ianto stood back and gave Sulu a small smile. "I think I can trust you with the taps. It's pretty straightforward, after all, you should be able to manage. C is for cold, and H is for hot, and all. And you don't even have to exert yourself and switch on the shower. It's really just as simple as that." Alright, so Ianto was being a little bit dry with his humor. He hoped Sulu didn't mind too much, though he did back off a little once he realized how he was being.

"Honestly, just make it a temperature that's comfortably warm for you. I'm so cold that anything above room temperature is going to feel pretty hot, so. It'll take some adjusting, regardless. ...warm for you, though. If it starts to get hot by your standards, then it'll definitely be hot by mine, and all." He smiled, this time a bit more sincerely. "D'you think you can handle that?"
