Puck, in Owen's voice, actually laughed a bit. Nothing loud, more of a chuckle. Like he remembered something funny but didn't want to get into the details. As Loki shared his offer and then demonstrated it, Puck kept his expression neutral. If he was going to demonstrate Owen, he needed to stay in the mannerisms. Otherwise the disguise had a higher chance of failure.
