Ianto nods mutely. Yes, he's fine. He's only just flashing back to some of the worst moments of his life, is all. But it's not his fault, he supposes. This other person -- robot? Lord even knows what he is, because Ianto certainly doesn't -- was just minding his own business, before Ianto had come along and interrupted.

"I, ehm," Ianto begins again, clearing his throat before trying again. "I was just. Looking for a friend. I didn't mean to. Interrupt..." Oh, he'd done a lot more than interrupt, and he's well aware of that, but admitting to it aloud would make the situation even more awkward, and there's only so much Ianto can handle at a time.
