I'm an irregular viewer and while I loved the season 4 finale, there is one bit I didn't understand. At the very end of the episode, all of these guys, apparently led by a woman, get out of vehicles and approach a house. My questions are:

a) Who is this woman?

b) Who are these guys?

c) Whose house are they at?

Thanks in advance!
