Worlds Collide in New "The Flash" Photos; EP Compares Wally West to Roy Harper

Team Flash -- or, at least, part of it -- has passed through the breach into Earth-2, and things there are a little different than what they're used to. A handful of new stills from "Welcome to Earth-2," the next episode of "The Flash," reveal some status quo shifts on the other side -- including a new, action-packed role and perhaps even an engagement for Iris West.

Additionally, executive producer Andrew Kreisberg addressed whether we'd see three speedsters at once at some point on the show. "I guess that could happen down the road," he told Entertainment Weekly, comparing the way Wally West might become Kid Flash to Roy Harper's development into Arsenal. "I wouldn't want to say no, but so much of that stuff is a little bit further into the future than we've planned for right now."
