While I imagine most of the action will still be in Hell, only a fool would dismiss the writing opportunities for Heaven. Sir Pentious has gone there, and he is likely going to be our eyes and ears in Heaven... and maybe Charlie's as well. So setting up a comm line with the Hotel is essential.
Molly, (and possibly her mother since Viv states that the only people in Angel's family who loved him were his sister and mother) needs to make a proper debut as well. If she and Sir Pentious can get in contact, he'll be able to tell her everything. But like most stories, I doubt the goal will be this simple. First off, there's the issue of Sera. Will she or will she not realize that she was wrong all these years and try to make amends? Or will she still be ruled by her fears and try to keep all this from happening?
And even if Sera is not an obstacle, there's another option HH could explore. Heaven in the bible, is a place where people forget everything bad that has ever happened to them. If winners have all lost their memories of all the bad in their lives, Molly may have no memory of Anthony. And if that's the case, a way must be found to restore every winner's memories. Because, if any of them remember friends or family members whom they loved, yet are in Hell, all Heaven could break out into riot or civil war.
So, any theories of how Sir Pentious and Emily can inform Molly of her brother? Should Sera be an obstacle? And if Winners have memory gaps, how will Sir Pentious avoid this if he can? And how will Molly and possibly Pentious find and restore everyone's memories?
