I think Ariel knew Hawkwind first. The girl from the commune said that Ariel ran off with her best friend. Hawkwind is a commune type of name and Mary said that she had to allow them marry even though they were so young.
I think she left Ariel, met Jamie, realised he was the good guy, married him and then was kidnapped by Ariel or ran away because of him at the airport. Ariel is obviously looking for her and her daughter, why he needed 3 places in the bunker. The general guy said that she betrayed him in Moscow.
I'm loving it, but missed most of the religious symbolisms. Do we know who is in the bunker?
Ariel/Jamie
Dave
Giraffe girl
Sister Celine
Scotty
Rhonda
And maybe lee-ann in the box? Did it sound like her?
Also, you would think the police would have more urgent concerns than finding an escaped librarian (even if they're convinced she's a cyber terrorist). The world in going to en in 20 days! Surely there are looters etc!
