Kirk was there helping Rose and Regina when he could, chatting with friends, trying to enjoy himself. Everyone with eyes has probably realized by now him and Rose are particularly close and he's kind of evasive on it if asked directly.
Molly was there and was friendly, if a little bit quieter than normal (I'm assuming by now she'd been compelled to sleep at least once, but probably not oten). But she did make it a point to introduce herself to people she doesn't know well and connect with friends she hadn't seen much of before the earthquake. And she adored playing with the boys.
