This week’s episode of The Flash is one fans have been waiting for all season, as the title – “Welcome to Earth-2” – lets you know.
IGN attended a press screening of the episode, part one of a two-parter, this week and it’s safe to say this is going to be an episode viewers will have a ton to talk about after. Jammed with Easter eggs, the episode makes full use of the different universe to introduce some notably altered incarnations of familiar characters and concepts from The Flash and the larger universe of DC shows it is a part of.
Describing the episode, Flash executive producer Todd Helbing — part of a writing duo with his brother, Aaron (the two wrote for Spartacus and Black Sails prior to The Flash) — said, “Barry, Cisco, and Harry go over to Earth-2 with a definitive plan that goes awry and they are left having to improvise. They find themselves in a completely different scenario than they anticipated – and have a race for their life to get back.”
