Sorry - I just realized that it was actually Kaylee's brother and mother/father that were killed and not a husbad, so I'd like to make adjustments to my second theory:

Theory two hinges around the "Isaac" that was mentioned in this week's episode. As far as I'm aware, we have no idea who Isaac is - just that he was important to Kaylee. So, similarily, my theory here is that Isaac was the nightblooded child of Kaylee (concieved in her host's body) or possibly her husband. I think Josephine, against Kaylee's wishes, used Isaac as a host for a different prime (maybe Gabriel?) and that was both what motived Kaylee to then kill Josephine (for having killed her son/husband) and also acted as the last straw for Gabriel, causing him to split off. Would also be good motive for Kaylee & family to run away, since she would know that when Josephine is "reborn" again she'd be able to tell the rest of the Primes than Kaylee was the one who caused her fall.
