The extended trailer that debuted yesterday for the first half of The CW's The Flash and Arrow crossover event showed that these powerful superheroes will eventually clash. Before that happens, though, a new clip showcases how Barry Allen (Grant Gustin) and Oliver Queen (Stephen Amell) work together as a team to stop the villainous Ray Bivolo (Patrick Sabongui). As you can see in the footage below, the metahuman Ray has the ability to control others by manipulating their emotions.

Flash and Arrow certainly seem to make a good team in this scene, where Barry saves Detective West (Jesse L. Martin) from a shotgun blast, while Oliver saves the day by subduing Bivolo. However, Barry's actions cause a rift in their relationship, as teased in the episode title and the previously released footage from yesterday. Who will come out on top? The Flash or Arrow? We'll find out in just a few short hours.

In addition, we also have a featurete, where executive producers Marc Guggenheim and Andrew Kreisberg offer their insight into this highly-anticipated crossover, along with new footage featuring characters from both shows. Check out the clip and featurette before tuning in to Flash vs. Arrow tonight at 8 PM ET on The CW.
