So i just watched the DD and PA kiss, for science purposes of course. I mean it screams friend kiss to me. First off she is clearly the one initiating (which hey if i was friends with dd id wanna initiate kissing him too) but also it is such a quick peck and the one hand on his cheek all screams friends. And then you have the cutting room where it really seems to me at least that the first one gillian initiates and the second one david initiates and they both last slightly longer then a peck ;)
