In season one we had the St. John's group, we had the Save Lots bandits group, we had the cancer survivors group, we had the remnants of the Crawford group, we had Lee's group, and some others.
Season two we have the cabin group so far, with Carvers group and the bandit group soon to come. We have a few theories of other groups like the cult in Ep 4 and Tavia's group from 400 days.
What other possible weird, interesting, or crazy groups do you see coming, how will they enter the story, and how will they affect the story?
