Note: This article contains spoilers for Crisis on Infinite Earths: Part 4.
It's actually happened: DC has just tied its TV and film universes together with an Arrowverse/Worlds of DC crossover.
As Crisis on Infinite Earths: Part 4 aired in the US on Tuesday night (January 14), Ezra Miller's Flash from Justice League turned up to make a surprise appearance – and even met Grant Gustin's own Flash at STAR Labs.
In the scene, Miller acts all confused meeting Gustin's version, asking: "What the hell is this?!"
"I'm asking myself the same question," replies Gustin.
Miller isn't sure where he is, then figures it must be cosplay and hilariously asks Gustin if he wants a selfie.

"I'm also The Flash," says Gustin.
But Miller doesn't know what he means (he goes by Barry Allen in Justice League).
They feel each other's outfits ("smooth and breathable"), then get freaked out when they both introduce themselves as Barry Allen.
Gustin says this should be "impossible now", but when Miller questions what he's talking about, Miller fades away before saying: "I told Victor this was possible." (Victor most likely being Victor Stone, aka Cyborg, from Justice League).
It was a funny, albeit shocking, scene that fans just could not believe happened.
The Flash airs on Tuesdays at 8/7c on The CW in the US. Sky One and NOW TV air the show in the UK.
