For those that have been tuning into CW's 'The Flash,' will recognize the showrunners doing something really special with these last few episodes.

A recent promo has been released for the series' upcoming episode, "Rogue Air," and it appears as if Team Flash enlists the help of a few common villains to help them deal with the Reverse Flash.

This may all result in a huge crossover episode, something 'The Flash' and 'Arrow' are infamous for. We get a scene that features Stephen Amell's Arrow and Robbie Amell's Firestorm on screen with The Flash.

From The Arrow's costume, it's apparent that they'll still be keeping true with the continuity of what's going on in his show, but hasn't yet been revealed as to how it will all tie in.

There is also a huge nod to comics with Wells summoning his Reverse Flash suit through his ring. For fans of both the series and comics, this episode is a must see.

The network provided this brief rundown to what we can expect to see:

"As Wells (Tom Cavanagh) once again gets the upper hand on the S.T.A.R. Labs team, Barry (Grant Gustin) realizes he needs to make a big move and reaches out to an old foe, Captain Cold (guest star Wentworth Miller), for help. Joe (Jesse L. Martin) and Caitlin (Danielle Panabaker) warn Barry that Cold can't be trusted. True to form, Cold has his own agenda that involves the meta-humans trapped in the containment cells. As things seem to be going from bad to worse, The Flash gets reinforcements - Arrow (guest star Stephen Amell) and Firestorm (guest star Robbie Amell)."

"Rogue Air" is set to premiere on May 12^th on the CW.
