QC's only wedding thus far has been about fairly minor characters, so what would it be like if people we knew better got hitched on-panel? Who would work best story-wise?
I would most like to see Steve/Cosette or Wil/Penelope. It would be a good way to bring them back into focus (Does Cosette even still work at the coffee shop? Is Wil even alive?), and they've been together longer than any of the other couples. Jim/Veronica might also make sense, given that they're the oldest main characters and both have been married before, so commitment isn't a new frontier for them. And Dora/Tai would be good, since they seem to have reached a point of stability and contentment.
I can't see Dale and Marigold ever having the motivation to get married. Marten and Claire still have a lot to go through as a couple, I think, and of COURSE Faye and Bubbles do.
(Please keep the discussion to established current relationships. I don't want this to degrade into crack shipping.)
