Wow, this was a very interesting mid-season finale. I still don't quite get all the details though. Suffice it to say, Eureka was where the first A-bomb tests really took place, and some radioactive 'purple liquid' was a byproduct, causing rapid aging...the cure was another atomic bomb explosion...?
I was wondering if one of the cast would be offed in this episode, it seemed like many cast members were put at risk. Eva did seem highest on the list, and apparently she was trying to commit suicide...
So Eva was '1 in a million' who the radiation didn't kill, but rather caused slowing of the aging process? They should study her biochemistry--could lead to an immortality vaccine or something. She was overcome with guilt, after years and years gets into a position to come back and bury what happened then? And she wants to die there, to honor the memory of her brother?
I'm guessing there was a 'Tuck Everlasting' situation where the immortality had become a curse to Eva, and she wanted to end her life?
I do wonder though whether the final reveal of Eva's story is ret-conned (in part). Eva's secrecy, carrying the vial around (why keep the deadly stuff if not to study it?), Zoe accidentally wanders in and gets infected (did she take adequate precautions?)...there's the rushed detonation (was it really worth the risk of earthquakes, radiation leaks, etc. which turned out to be a real consequence?). It's all a bit weird to me, I wonder how it stands up to close scrutiny. Not sure if I can fully accept Eva's motivations as they were explained. Why not invent some cover story, instead of insisting on such secrecy, redacting things, and just inciting more and more curiosity?
But, in the end I grew to appreciate Frances Fisher and what she brought to the role. Having only seen her as a mean mother figure in Titanic and the Audrey Hepburn Story, I was pleasantly surprised to see her role in Eureka. I hope she returns, but wonder what kind of storyline they would give her now that the secret is out.
