If the latest pulse-pounding trailer wasn’t enough for you, DC All Access has given us a deeper look at tonight’s episode of The Flash. And while it doesn’t spoil too much, the footage showcases a pivotal scene as the crossover goes into full swing.

What makes this clip so special is that we see Barry Allen save Green Arrow and Spartan from a hail of gunfire courtesy of Vigilante and literally drag them into his current predicament. In addition to letting them know how dire the situation is, Thea’s motivation for once again donning her Speedy costume can be seen. Personally, I was quite amused to hear Oliver make a joke about helping Barry with “another evil speedster.”

Granted, things won’t get much easier for these folks once this whole invasion thing blows over, but we recently learned that the Dominators aren’t done with Supergirl. Hey, nobody ever said being a superhero had no complications.

For more information regarding tonight’s episode, please consult the official synopsis below:

“When aliens called the Dominators attack Central City, Barry (Grant Gustin) speeds over to Star City to ask the Green Arrow (guest star Stephen Amell) for help in stopping them. Realizing the battle against the Dominators is bigger than they thought, they track down the Legends of Tomorrow, and Barry and Cisco (Carlos Valdes) create a breach to bring back a secret weapon – Supergirl (guest star Melissa Benoist). Once all of the super friends are assembled, they come up with a plan to attack but a shocking secret related to Flashpoint is revealed and suddenly no one is sure who they can trust. Meanwhile, Wally (Keiynan Lonsdale) wants to join the battle against the aliens but Iris (Candice Patton) tells him he’s not ready.”

The Flash airs on Tuesday nights on The CW.
