"It's all right, though. You've been doing better." Well. Ianto had been doing better, before the 456. But right now wasn't so bad an attempt at being happy either, even if the tea was playing a role in that. And hopefully, when he got better and was able to go out again, this sort of attitude would return in full force. He was depending on that hope, right now - that Ianto would be more optimistic when he got better, and that Ianto would get better at all.

"And really, it doesn't matter how depressing you are. I'm with you in spite of all that, you know." He smiled at Ianto. "I don't mind having to put in the extra work to make you feel better about yourself and life in general."
