As soon as the words are out of Ianto's mouth, Ianto recognizes that something is wrong. There's something about the look on John's face, the way he's holding himself, that instantly has Ianto on edge. It's not a look he's seen on the other man before, ever and he instantly surges into action himself. Moving to take another step closer, intent on coming to his aid in some way.

Which is when John pops up and pulls his gun on him, of course. Not the way Ianto had anticipated this interaction progressing.

Ianto raises his hands in front of him, instantly on the alert. It's not the first time he's ever had a gun pointed at him, but it's the first time it's ever come from John. Instantly very aware that he's nowhere near trained to handle any sort of face off with the other man, and his own stun gun is still packed in his bag from earlier in the day.

"John...?" he asks, carefully. "Why don't you -- put the gun down, yeah? Let's just. Talk. Did something happen?"

He tries to remind himself to breathe. In through the nose, out through the mouth. Slowly, slowly. This. Isn't what it looks like. Is it?
