[Jack is also most recently from before 50 Shades of Grey, but he also knows a lot of things from his time as a Time Agent and 50 Shades is one of those phrases that's stuck around. So he gives Kitty a wry glance as he climbs onto the bed and scoots over to kneel beside Ianto.] This is probably the least dramatic man you'll ever meet. [He doesn't add that he's one of the most dramatic, because she's almost certainly figured that out for herself already.
He makes short work of fastening Ianto's wrists behind his back with the chain of the cuffs passed back through the bars so he's not going anywhere. The work is comforting, and it's not until he's finished and crossing the room to place the key to the cuffs on top of the wardrobe (no way he's keeping it in his pocket from where Ianto might be able to lift it) that he realises he has no idea what to do with now. At the very least, he's got the rest of the night to get through with this Ianto - and he's hardly daring to think ahead and hope that this really is just for one day only - and... what the hell does he do with it?
Try to understand, that's what. He leans against the wardrobe and crosses his arms, studying Ianto.]
When did all this start, Ianto? What triggered it?
