[He's been brought here to fight a war without choice, away from the king he follows, and it's not even a good time of year. There's snow on the ground and he's not really dressed for it in his leather and cloth but in the grand scheme of things it's a small price to pay really to be like this and the children are happy so he can't complain about that. In fact it's rather thrilling to know that children, somewhere, are happy even if it's not Camelot at the moment.
So really it's with a grin, after several moments of contemplation at his situation because he could get rather deep into his thoughts or go off yelling at some unseen person, that he decides on something more fun. That being to bend down with his shield over his head to cover him as he scoops up a handful of snow to throw at the nearest person. Without looking naturally at the person before him as he throws it.]
