20 Awesome DC TV Easter Eggs You Probably Missed
16. Journey To Atlantis (The Flash)
The Flash isn't shy when it comes to name-dropping, and in Season 2 there was one big location that they heavily teased: Atlantis. While Earth-1 knows it only as the fabled lost city, over on Earth-2 it's an actual place that you can visit. Barry (of Earth-2) gets his parents tickets there, because they've always wanted to go, and in the follow-up episode, he and Iris plan on fleeing there themselves. Jay Garrick also mentions the place, saying he loves it and that one of his best friends is from there.
Who could that be? Well, Atlantis just so happens to be home of Aquaman, a fellow Justice League member. While it's unlikely he'll ever appear on the show, due to the film side of things not sharing, it's still fun to know he possibly exists in this world.
