Phillip did half expect to be thrown off or pushed away, still deeply uncertain of where this puts the two of them. He has no quarrel with Gustavain or what he's done, what he means to do, other than it being an incredibly foolish thing to take on alone and he doesn't wish to see him come to harm. But even though he has argued his case on how he is not the sort of Ascian that has hunted him down, he wasn't sure that would be returned.

Therefore, the kiss is something of a surprise to him, but other than a curious noise when their lips connect he doesn't have any objection to it. He leans into it, still a little cautious, but much of his own tension beginning to release as they hold onto each other and he continues to stroke that long, fine hair. He still doesn't know where this is going. But... perhaps he should just let them be for a time.
