5 Thoughts On Stephen Amell, Grant Gustin's 'The Flash/Arrow' CW Crossover Promo!

The CW network continues with Season 2 of The Flash and Season 4 of Arrow. In the newly released Arrow/Flash crossover promo, this the perfect opportunity to check out Barry Allen (Grant Gustin) and Oliver Queen (Stephen Amell) what's in store from the trailer footage.

In the previous crossover, Arrow (Amell) and The Flash (Gustin) ended up on opposite sides as Rainbow Raider screwed around with the scarlet speedster's mind. The Flash and Arrow had to fight each other before taking down the meta-human. But things changed the second time around, when Arrow needed the Flash's help to take down Captain Cold. Not only did they manage to work together, the two gained mutual respect for each other.

Check out out 5 thoughts on the Flash/Arrow crossover trailer here:

1) One Big Bad!

As we previously mentioned, Part 1 is entitled, Legends of Today, which follows Vandal Savage (Casper Crump) as he arrives in Central City. The immortal super villain sets his sights on Kendra Saunders (Ciara Renée). Cisco (Carlos Valdes) is caught in the middle when Hawkman (Falk Hentschel) spreads his wings and takes Kendra.

Bonus: And what the hell?!? Did Kendra just sprout wings?

2) More Big Bads

We also mentioned, Part 2 moves the action to the renamed Star City in Legends of Yesterday. Realizing how dangerous Vandal is, Barry moves Kendra to Star City and asks Oliver for help. When Malcolm Merlyn (John Barrowman) gets involved, things don't go exactly as planned. Whose side will Malcolm eventually join, Team Arrow or Team Savage?

Bonus: With Arrow and Vandal shooting at each other, will the Flash be able to stop the throwing knives from hurting his friends?

3) Cisco The Ladies Man

First, Cisco gets a passionate kiss from Lisa Snart (Peyton List) after saving her life. Then Cisco gets Kendra's number after trying to flirt with her. So what the hell could ruin Cisco's mojo? Hawkman (Hentschel) ruins the winning streak by being the biggest and douche-iest c*ck-blocker on the planet!

4) Everybody's In Costume!

Thea (Willa Holland) is getting involved this time around as Speedy aka Red Arrow. Even Laurel (Katie Cassidy) is going to dress up as the Black Canary. Even Diggle (David Ramsey) has his...Magneto helmet? You get my point! Everybody is going to step into the ring and fight in costume!

5) Did That Bomb Explode?

My favorite part of the first crossover was when Barry had to stop the detonation of Captain Boomerang's bombs. Straight from the comics, the scarlet speedster has to be at five different places at the same time, in order to deactivate the explosives. On the TV show, it was really about teamwork; not one man getting all the glory. How is the crossover sequel going to top that sequence?

The Flash continues Season 2 on the CW Tuesdays at 8pm. Arrow continues Season 4 on the CW Wednesdays at 9pm.

Legends of Today airs December 1 and Legends of Yesterday follows December 2.

Readers, what do you think of the crossover between Green Arrow and the Flash?
