It looks like Felicity Smoak and Ray Palmer will be paying a visit to Central City, with Variety revealing that Emily Bett Rickards and Brandon Routh are to make guest appearances in the upcoming eighteenth episode of The Flash, entitled ‘All Star-Team-Up’.
“In episode four of Flash when Felicity came by, it wasn’t just a gag to have Felicity come by,” states executive producer Andrew Kreisberg. “It really was integrated into the story. When you reach what’s going on in The Flash at that point in the season, Barry is really at a crossroads. Having Felicity come by exactly when he needs her really plays into the whole storyline. It’s fine because as Marc [Guggenheim] said, Ray Palmer is all about technology and STAR Labs is all about technology. We get to see Ray so happy to be in STAR Labs… With Cisco [Carlos Valdes] and Ray, they’re new best friends. The STAR Labs team is going to help Ray further his ATOM project.”
“I’ve thought about [the crossover], because I’m a Flash fan for sure — it’s a fun show and the energy of that show jives more with Ray’s energy, so I think he’ll definitely be a kid in a candy store over there, checking out all of their cool equipment and everything they have going on,” adds Routh.
