But don't assume that means The Flash is going to cool off with the epic episodes and action after this one, because Cavanagh promises that it only gets bigger and better from here.

"What's been so impressive for us is that this is a really strong episode of television, and the ones to come, we're spring boarding off it," Cavanagh says. "The danger is if it's a pinnacle and you slide back down but this is not the case. We have large and small moments coming that use this as a starting point to build toward our season finale, which is also something to be reckoned with. It escalates nicely."

And speaking of the actual season finale, Candice Patton warns that fans have no idea what's coming as we near the end of the season.

"When I read this episode I remember thinking, ‘Where can we go from here? We gave everything away! What can we possibly do?'" Patton, who plays Iris, says. "But Andrew always says, 'Use what you have now and we'll think of new ideas later.' So if we're going to do this in episode 15, you can only imagine what the season finale is going to be like."
