We’ve already seen a Flash/Arrow crossover this season, and now Felicity will be returning to Central City and she’s bringing Ray Palmer with her.
It’ll go down in Episode 18 where Ray decides he needs to geek out with the STAR Labs people to get his Atom suit working, and Felicity will help Barry out with some crisis he’s going through. THR explains:
â€œIt happens to come at a particularly bad moment for Barry, but thatâ€™s partially why we did it. The first episode with Felicity in episode four, she really came along in a time when her experience in being a part of a crime-fighting team definitely helped Barry overcome what he was facing that week,â€ said Kreisberg. “When she comes [back], heâ€™s having a crisis of conscience that in some ways only someone like she can help him through.â€
As for an another Arrow/Flash crossover? That’s already been confirmed as something that will happen every season on the show.
It’ll be cool to see Felicity with Barry again. I know Tumblr is obsessed with “Olicity”, but the last episode she was on showed it should be Barry/Felicity.
