His drunk... "That would be the one," Ianto says, flicking Jim a smile, completely oblivious as to their latest interaction which is perhaps probably for the best given the circumstances.

Jim's following invitation confuses him for a moment -- hadn't he just said that he could stay here? -- until he realizes, "Oh, you mean. While you're in Olympia?" The offer surprises him for its simple generosity yes. And it's trust in him as well. This is his home, after all, no matter the size or state of it. Ianto keeps that in mind even if Jim may be rather casual on the matter.

"Are you...sure?" he asks hesitantly, a little in awe of the generosity of the offer in truth.
