After two bizarre trailers from The CW this week teasing the "Elseworlds" crossover, a lot of questions are being answered regarding the upcoming Arrow-verse special. Those who guessed that Earth 1's Barry Allen and Oliver Queen had swapped lives were correct, but there's so much more to the story than that. It turns out this whole scheme is the work of Arkham Asylum doc John Deegan, who kicks the story off by "rewriting reality."
The plot thickens as the mysterious Arkham Asylum doctor is revealed to be the cause of Barry and Oliver's switcharoo. How does he do that exactly? That much is unclear, although EW's reveal does show how Gotham City will work its way into the picture. It seems as though the flip-flopped heroes will have to go through Gotham to get to the bottom of what led to their switch.
Though Barry and Oliver swapped lives and powers, fans won't get to see the two men doing a bit of role-playing in each other's shoes. Grant Gustin confirmed he won't be emulating Stephen Amell's mannerisms or vice versa. That makes sense considering they're both their regular selves, although it is a bit disappointing to hear that fans may not get to see Gustin attempt the iconic salmon ladder routine.
The report also confirmed the heroes are the only two people on their Earth who seem to realize it, which is where Supergirl comes into the picture. For some reason, she's able to recognize them and understand that things aren't as they seem. This leads to some scenes between the three, which Marc Guggenheim mentioned was rare in last year's crossover.
It's a positive side effect of the "Elseworlds" crossover's decision to exclude the Legends of Tomorrow. The series was left out of the fun this year, as Guggenheim added that the exclusion put less stress on creating and filming a fourth hour and a crossover with a larger cast. That said, Guggenheim revealed the show wasn't left entirely out of the loop and that hour three of the crossover will feature a Legends cameo.
It was also revealed that "Elseworlds" will feel more episodic than last year's "Crisis On Earth-X." Todd Helbing said each episode will feel like its respective show, meaning The Flash will feel like The Flash and so on and so forth. The result is a crossover Grant Gustin is especially proud of.
