Wednesday evening, the flash ended after nine seasons on The CW with “A New World, Part Four” bringing together multiple storylines and storylines as the Arrowverse series wrapped up Barry Allen’s story. Among the items included in the series finale was the delivery of a longtime fan theory about one of The Flash’s most interesting foes in the comics – albeit with a very the flash twist.
Warning: spoilers for the flash series finale, “A New World, Part Four” beyond this point.
In last week’s penultimate episode of the series, Eddie Thawne (Rick Cosnett) came back to life in 2049, but is soon tempted by the Negative Speed Force with his mysterious blue crystal, telling him that Barry Allen (Grant Gustin) is neither his friend nor his ally, but that Barry took the life he should have had and that his Season 1 sacrifice meant nothing. The episode ended with Eddie being drawn to the crystal, but we didn’t see him fully kiss it. This changes in the series finale. Home of the West – or rather the manifestation of the Negative Speed Force, Eddie not only assembles Godpseed, Reverse-Thawne, Savitar and Zoom, but he embraces the crystal and becomes the avatar of the Negative Speed Force and calls himself Cobalt Blue, complete with a comic book-accurate costume.
“Rick’s another one that blew my mind,” Gustin said “of Cosnett’s appearance before. “I mean, we had some really cool scenes the last two episodes and he kind of ran the bet with his performance in the latter. I mean, he must be doing some really interesting stuff. There was some really fun stuff for him. It’s unlike anything he’s done on our show before and I think from the conversations I’ve had with him it’s unlike anything he’s done in his career. I mean, he really did a lot of fun things in the last two episodes and he really impressed me.”
Eddie’s transformation into Cobalt Blue delivers something fans have been hoping to see since the start of the series, though it does so with a bit of a twist. In the comics, Cobalt Blue is Malcolm Thawne – Barry Allen’s secret twin brother who was stolen from the Allens at birth and given to the Thawnes. On The Flash, Eddie isn’t Barry’s secret twin – he’s really just Eddie Thawne – but his motivation for hating Barry is the same (although Eddie’s is also manipulated by the Negative Speed Force ): he feels like Barry has taken the life he should have had.
However, while the flash finally giving fans the arrival of Cobalt Blue in what is the final battle for Barry Allen fulfills this fan theory and fan desire, it’s a bit bittersweet as to its timing. With that coming in the series finale, Cobalt Blue’s time on The Flash is short-lived. Barry is eventually able to work out some sort of truce with Eddie, convincing him to remain the Negative Speed Force’s avatar so they can co-exist, but not give in to his anger, thus saving reality from her. -even.
