All Arrow fans got surprised when the first promo for the “Elseworlds” crossover event premiered yesterday.

The first teaser for the three-episode crossover event debuted on the CW and while it didn’t reveal much, it confirmed that Oliver Queen and Barry Allen will swap identities. The promo shared a scene which featured Iris West giving Oliver a kiss, proceeding to tell “Barry Allen” how much she loves him.

This identity swap is something that has been teased earlier through posters and behind the scenes peeks, along with a tweet from Stephen Amell earlier which said, “My name is Barry Allen and I am the fastest man alive,” which he followed up with “this is real, btw. I’m in the Flash suit while I type this.”

It turns out that this was, in fact, very real. Many fans have taken to social media to react to the teaser and now with this promo, reactions have ranged from shock and surprise to near-horror. Here’s what Amell said about the crossover during his Facebook live session.

“The crossover is freaking bananas,” Amell explained during a recent Facebook Live. “It’s crazy… I think that this will be the best crossover event that we do. And not just the best but the best by a really, really wide margin. And I think that last year was fantastic.”

“‘Crisis on Earth X’, I think that’s what it was called, that was pretty crazy and getting to play doppelgängers was pretty crazy,” Amell continued. “When Greg Berlanti first talked to me about why he wanted to do crossovers, it was because it’s for the fans. It’s so people can watch characters and scenarios that combine their favorite things on TV or introduce them to new things on TV. But you also get this license to do things that we could never do in the vacuum — especially on Arrow — that we can never do in the vacuum of just our show.”
