And it is that sobriety that catches Lorne off-guard enough that another errant snowball almost completely escapes his attention. Lorne spots movement out of the corner of his eye and only barely has time to turn and attempt to jerk out of the way. The snowball still lands, spraying his shoulder and the exposed skin on his face yet again, which is a step up to having it hit his ear.

...the Shepherd definitely distracted him to help the kids. This occurs belatedly, confusion registering over the fond resignation at being pelted with snowballs for the next little while, and he spares the man a faintly incredulous look. Surely if he's willing to assist in a snowball ambush, this Shepherd won't begrudge Lorne disbelief.

He'll have to examine that later; more snowballs are following the first, and since they've no longer the element of surprise the children have resorted to quantity over subtlety. There are more of them than Lorne, but he does have the boon of superior aim and arm strength on his side. Unlike them, however, he's not aiming for anyone's head. That would just be unfair of him. If there's a smile on his face, it's patient and one he's practiced at minimizing - Lorne has long been accustomed to the shenanigans of younger children.
