"Mmhmm." Now it's Ianto's turn to give Jim the side-eye and a knowing smile. He knows avoidance tactics when he sees them. He knows your type, Jim. (What did we say about him having a type again?) He's pleased with himself to have gotten this right for a few moments before he processes the rest of what Jim is saying and then he just looks mostly confused.

"I'm sorry," he says, holding a hand up for Jim to go back a bit. "You ran into an old friend -- in a cave in the middle of a frozen wasteland after being chased by giant bug aliens?"

Does he sound a bit disbelieving? It's because he is a bit, rather. It's one hell of a story, anyway. "Do you make a habit of friending people who get themselves exiled to such places then?" he quips, albeit warm-naturedly.
