When we left last season (or part-season; I can never get these syfy "seasons" straight), Jo, the testosterone-fueled deputy sheriff was in love with the cute but devious town rogue;
her boss, Jack, had moved on from his unrequited feelings for Allison (head of the Department of Defense-connected Global Dynamics, the corporation that runs the town), only to find that the woman he moved on with, Tess, is leaving him for a job in Australia;
Allison, whose remarriage to Jack's rival ended in disaster, is left alone to take care for a newborn and an older, autistic son.
This season opened with the same players in place. Tess is gone, Allison is a single mother, and Jo's boyfriend has just proposed. Hocus-pocus (and a lot of scientific jargon) and they are all whisked away to 1940s Eureka. High adventure ensues, including the long-awaited reconciliation between Jack and Allison.
But, as many sci-fi series have noted, you can't come back from the past without changing the present, so when the parties return, everything is different.
To Jo's horror, she is now overweight and the last person her boyfriend would marry, he isn't even her boyfriend; Tess not only didn't leave for Australia, she has (or is) moving in with a dismayed Jack, and Allison's autistic son has been miraculously cured--giving her a stake in maintaining this new present, as opposed to the others who can't wait to ditch it for the old one.
I enjoy this show, but it's not at the top of my list. But I have to say that this plot twist was pure genius, Eureka style.
It shakes up all the relationships and gives them a second wind. The inevitable doldrums of happiness that come with finding true love is avoided. Now Jo and boyfriend are back at ground zero--as are Allison and Jack.
And there's more. Henry, the town's jack-of-all-trades, is suddenly married--to someone he never met before.
And Fargo, the nerd-prone junior scientist, everyone (including the audience) dismisses, is now head of Global Dynamics.
Can't wait to see how all these new twists play out. I only hope they don't give in and turn everything back to the way it was too soon.
In the meantime, kudos to whoever came up with this plot device. I would loved to have been a fly on the wall of the writing room.
