Barry could either save his mother's life and, in the process, spare the Earth a gigantic black hole, or let his mother die and, in the process, sick a black hole on the planet. He chose dead mom and black hole. Pretty convoluted. They never explained just why Eobard hated Barry so much, but if Barry chose all that…

Sounds like you're championing intelligent design…

Metabolically, he probably should age much faster than normal. I suppose its the rapid metabolism vs. the rapid healing, and the healing wins out.

Oliver was the fun guy before all this.

Surely there's at least one of the infinite Earths where Eddie did just neuter himself instead of killing himself…

The residents of Starling are looking at the wormhole over Central City on the news and thinking mkay this bioscare maybe wasn't a so bad.

She'll get to go full camp as a villain and still keep her original character, like Nana Visitor and others got to do in the ST mirror universe.

You'd think the wormhole would just resurrect Eddie and bestow immortality on him…would be easier.

Yeah there really needed to be a timewave like in Voyager's Year of Hell that washed over everything and undid any effect Eobard might have had on it. I suppose they decided to go wormhole instead.

Real World: DC (not the Washington one)

Jurassic Park

Well the same writers wrote Oliver letting Malcolm become Ra's al Ghul with little more than a not very stern warning, so…

I thought there was also dialogue about "500 years in the future". Eobard was apparently born in 2151, so even the "dead for centuries" comment he threw around all season suggests that Eobard's age was pretty old - like triple digits at least - at the point he left his time. It's 2015 now, so someone who died in 2015…

Hopefully.

"The way things end for Eobard I'd say no, but Tom Cavanagh is too big of a name and too important to the show to let him go"

Not a comic book reader,so how does Earth-One and Earth-Two work…can a resident of one vacation in the other?

This argument is similar to the Tuvix argument from Star Trek Voyager…the right of Tuvok and Neelix to be restored vs. the right of Tuvix to continue to exist. There is a conflict of rights involved, but in all such cases some verdict has to be made; something has to be done/undone or not. I side in both cases with…

That was the missing factor here.

Now that pop classics are apparently going to feature on this show, at the end when they showed Cold and others looking up at the thing, I thought they might have started playing Black Hole Sun…

That wormhole special effect seemed every bit as good as the one from Avengers…
