Only four episodes in, and 'Arrow' spinoff 'The Flash' is already bringing in the big guns for its first crossover, and by big guns, we of course mean the badass Ms. Felicity Smoak. The Arrow's best gal will take a trip to Central City next week for "Going Rogue," encountering the chilly Captain Cold in the process, and we've got the first photos!

Much as we'd like to see Felicity and Barry given a happy ending all their own (now that Oliver's perpetually grumpy), the Central City reunion of "Going Rogue" will prove none too smooth-going. In fact, the only smooth surfaces will be those caused by the arrival of Leonard Snart (Wentworth Miller), who conjures up a chilling manner of slowing down The Flash's crime-fighting enterprises.

Meanwhile, here's how The CW describes next week's "Going Rogue":

WENTWORTH MILLER GUEST STARS AS DC COMICS’ VILLAIN CAPTAIN COLD

The Flash (Grant Gustin) stops a robbery but the culprits get away after shooting a guard, and The Flash chooses to save the man instead of following the criminals. Joe (Jesse L. Martin) shows Barry a book of suspects and Barry identifies Leonard Snart (guest star Wentworth Miller, “Prison Break”) as the leader of the group. Snart revises his plan to steal the Kahndaq Dynasty Diamond and gets a boost when he gets his hands on a stolen “cold gun,” which could kill The Flash.

Dr. Wells (Tom Cavanagh) is furious when he finds out that Cisco (Carlos Valdes) built the cold gun without telling anyone and now it’s missing. Meanwhile, Iris (Candice Patton) is getting the silent treatment from Joe because of her relationship with Eddie (Rick Cosnett). Finally, The Flash and Captain Cold have an epic confrontation.

It looks as if Cisco and Caitlin get in on the action by the photos, but what do we think? Until we see the epic battle of "Flash Vs. Arrow," will Felicity hold her own against Captain Cold? Check out the full set of photos below, and give us your take on 'The Flash' thus far in the comments!
