Once he gets to the point where he knows you like them, Serph, there will be less asking, don't worry. Jack grins, pauses long enough to set his food stuff down, and then bounces over to wrap his arms around Serph's waist in a hug. It's either go over the wings or under the wings, and under seems safer, and also less likely to wind up with Jack having to stand on his toes to manage a proper hug.

He is, in fact, pretty good at hugs. He's had a lot of experience.
