Jenna and Serenity

So I'm going to make a prediction and then back it up with some stuff.
I think this book is going to end without finding Alice alive, and with Serenity adopting Jenna.
Why?
Because Jenna hasn't seen her parents (lucid, that is) in years, her grandmother is absolutely not acting as a mother- she's acting as a caretaker at best, Serenity is weird, Jenna is weird, Serenity had all that motherly stuff in her car like junk food and knitting, and then there's that massive thing on 182 where Serenity catches Jenna and realizes that she needs a mother and Jenna kinda flips out a little. They are all hip together, and they had a fight but they keep reconnecting, and maybe this could be Serenity's spirit guides trying to do something good for her.
I don't think they would break however many years of silence so some annoying kid can find her super-shady mom. I think they are breaking their vow to not help her because the other side knows that she and Jenna need each other. This is more supernatural than most Picoult books, but I think we are about far enough in to start getting hints to the big twist.
I don't think this is going to be a simple mother-daughter re-connection anymore. I think there is something more going on.

Plus... Jenna's "in absentia" thing that she keeps saying about how she makes elephants seems to point to some other "in absentia" thing, like spirit guide help.
