Being called 'Jack' and not 'sir', gave the captain a slight hint as to the timeline Ianto could had been pulled from. Not a large one, mind, but theoretically enough of one. In all actuality it told him absolutely nothing and it was Jack's own foolish hope attempting mould the situation to suit his own needs and wants. Not like that hadn't happened before. Yet Ianto's presence (no matter from when), soothed Jack in ways he couldn't explain. There was something about the suit, coloured shirt, and the accent that could calm the worst of Jack's irritability. At least there was one person on his side for the never-ending battle of Suzie and the Glove vs Jack, round 4204.
Thankfully.
"A few hours?" Jack asked, lifting an eyebrow in his direction. "Knowing one Ianto Jones as I do, 'a while' is code for 'longer than I care to admit'." His tone was light, teasing, eyes glancing back and forth between the file and the man who stood before him. "Some of that would be my fault." Jack gestured to the stack of papers crowding the left hand side of his desk. "All right, most of it would be my fault."
Then again... His mind flicked to Suzie the moment Ianto brought her up. "What files?" Jack asked, all trace of amusement gone from his face. "I told her she was not to start experimenting. If she's going behind my back so help me--" Jack broke off before he left the office and throttled Suzie. Six deep breaths later and he sank back into his chair, unaware he had risen from it in his anger. Jack sat, lips pursed, and looked up at Ianto. "I take it you've seen her, then." It wasn't a question.
