No, no he really is not comfortable with it at all, but he is trying to put on a brave face. He used to catch aliens for a living, he had had no problem shooting them before. Of course, they had been trying to invade his planet and/or kill him. These lizards were... Well, not harmless, but. Literally going out of his way to have to kill them is another matter entirely.

"Yeah, alright."

Ianto glances aside at the other man again, hooking the straps of his bag higher on his shoulders before sticking his hands deep into his pockets. It's not Nadril, but the air still holds a chill at this time of year.

"Well. Nothing like a day of poisonous lizard hunting to get the blood flowing," Ianto quips, idly. Perhaps because he is uncomfortable with the idea of it. Perhaps because he's uncomfortable in general.
