Ianto looked up at Jack's face as the older man spoke, nodding. He missed Jack from his point in time, but this was still Jack and he still had all the qualities he loved about Jack. Maybe he'd never get back to his own time, but he didn't have to lose everything.
"They're right...it does," he agreed softly, just enjoying the feeling of Jack holding him. He knew he should let Jack know the Doctor was here, that he could get his answers again, but he wouldn't just yet. He was allowed to be a little selfish, and he didn't want Jack running off again and leaving him alone.
"Jack," he said, slightly nervous, calling the other man by his first name for the first time since he'd realised they were from difference points in time, "as far as I know, almost everyone I care about could be dead right now. And if I think about that I might go mental. So, can we just stop talking right now?" And he pulled Jack down into another kiss.
