This week's episode of The Flash was packed full of Easter eggs, cameos, and super alter-egos thanks to our hero's trip to the parallel world of Earth-2, but the show isn't ready to leave that world behind just yet. There's so much more to explore, whether it's how Earth-1 Barry and Cisco will respond to the things they've seen and the people they've met, what's going on back on Earth-1, or the fallout from the previous episode's final moments.

With that in mind, THR talked to The Flash executive producers Aaron and Todd Helbing, who dug into each of these questions and more. They looked back on "Welcome to Earth-2" before teasing what's about to befall Barry Allen and his friends in the upcoming episode, "Escape from Earth-2." If you need a refresher on the last hour of The Flash be sure to read over my recap before seeing what the Helbings had to say. If you haven't caught up with The Flash, you should probably avoid the following conversation due to spoilers.
