Honestly, TJ has no actual interest in breaking up whatever it is the two men have between them and she holds up her hands in a gesture of surrender as Ianto pats John's arm in that gesture of consolation.

"I'm just trying to make friends," she tells him, her tone as sincere as she can possibly make it. "That and your military background, I was hoping for a heads up on anything else you might know. Any other military types? Is there a command structure of some sort?" Do they all just fend for themselves? He does outrank her, after all.

She looks over at Ianto and, still trying to make sure she's not stepping on any New Friend toes, adds, "I'll be grateful for anything, if you wanna share it."
