Lom-Lom, there are no retractable votes; and I think that nothing happens if the GW is chosen by the wolves. Hunter-variable is down to LMP, but Hunters have been known to have a free kill regardless of who kills them in the past (Mormegil slaying Abercrombie immediately comes to my mind!).
Does "be betrothed" even make sense? Why am I using words that I don't know how to use? And Cailín: I presume you meant: "How did we ever manage to produce two such improbably wonderful sons?"
