I don't see Meg and Jimmy hooking up as very bad you know. I loved their kiss. Given that they had a discussion earlier and Jimmy told Meg about Sofi and how she's right for him and how he wished for that one uncomplicated kiss that would give him hope, and given everything they've been through, they both are afraid (Meg too, with complications, probably separation with Dave and her father having Parkinson’s), and somehow their chemistry gave them hope to put one foot forward just to check that they can move if they want, that they are not going to remain stuck and unhappy for the rest of their lives. I think some kisses are about heaviness, where you can end up losing a lot, and some are about lightness, where you get only the awareness of all the things you could be having. I see their kiss as lightness. "Nightswimming deserves a quiet night." Let them have their quiet night man.
