One moment they are standing and Phillip is making his quip and then there's a flash of a grin and he's sprawled face down on the ground instead, Gustavain moving with that same surprising grace and speed, kicking his feet out from under him. It's not gentle or controlled, it's possible he's going to get bruises or the air knocked out of him from it, in fact, but it's not meant to cause further hurt. Gustavain has those gloved hands on his hips a moment later and he drags him bodily up to his knees, the grind against his ass a moment later more about the psychology of it than anything else, blatant and animalistic.

So, too, is the bite into his neck right near the meat of his shoulder a moment later, more like a wolf bite than a man's, like Gustavain could hold him still with his teeth there, lest he tear out his throat. The truth is more a show of danger than actually dangerous, his teeth are no sharper like this than normal, but it will bruise, likely vividly.
