Um. And mum.
Elizabeth Mitchel is not to be wasted on Flashbacks.
They'll figure out mum is alive half way through season one, a couple episodes later the daughter understands that uncle and daddy both dated mum and they all had a big fight about her final choice... Then they find mum in the last episode and she gives them their quest to turn the world back on, but daughter says "screw that, this world is better". And... Curtain.
It's a standard formulae.
hey, this tech darkage is almost like what Snake Plisken did in End of Escape from LA.
