5 Reasons To Watch Grant Gustin, Brandon Routh, Emily Bett Rickards On CW's 'The Flash' Ep 18! [WATCH]

The CW network is putting together another Arrow crossover on The Flash. In episode 18, will Barry Allen (Grant Gustin) and Ray Palmer (Brandon Routh) be able to work together to save Felicity Smoak (Emily Bett Rickards) from the super villain, The Bug-Eyed Bandit (Emily Kinney)?

In Felicity's first appearance, Barry (Gustin) needed help when Captain Cold (Wentworth Miller) stole one of Cisco (Carlos Valdes)'s inventions. Barry was personally hut when he discovered Cisco made a freeze ray that could permanently stop him, in case he went bad. Felicity reminded Barry that Cisco and Caitlin Snow (Danielle Panabaker) were his friends and they would be there for him when things turned out bad.

In Felicity's second appearance, the scarlet speedster teamed up with Arrow (Stephen Amell) to take down the Rainbow Raider. When the Rainbow Raider messed with the Flash's head, it was up to Arrow to bring him back to his senses. The Flash then arrived in the nick of time to save Arrow from Captain Boomerang's deadly weapons.

Here are 5 reasons why we're excited to see The Atom and The Flash crossover:

5) The Bromance

The Superman Returns actor has just been killing it as Ray Palmer on Arrow. With Ray and Cisco (Carlos Valdes) being two of the quirkiest geniuses around, the super suit will become ten times better. Supposedly, these two are going to become the best of friends. I can't wait to see how that happens!

4) Super-Friends

This isn't like Green Arrow taking on the scarlet speedster, which was like Batman versus Superman. Since they both care so much about Felicity, The Flash and The Atom can actually work together on this to save the day. Ever since Firestorm showed up, it does feel like the CW is putting together their own version of the Justice League on the small screen.

3) That Dinner Date

As we perviously mentioned, there's going to be a date night with Barry, Ray, Felicity, Iris ,and Eddie all involved. It can only end in an epic and awkward disaster. This scene is going to be funny on so many levels.

2) Beth Greene Lives

Were you just as sad as I was when Beth died on The Walking Dead? It's so nice to see Emily Kinney back on television again, this time playing a DC Comics baddie. I really liked how the show writers flip-flopped genders around, turning Bertram Larvan into Brie Larvan. Does this mean Kinney will eventually show up on The Flash/Arrow spinoff.

1) Whose Side Are They On?

In our recent recap, through flashbacks, the Reverse-Flash revealed himself to be Eobard Thawne (Matt Letscher), a murderer displaced in time. After causing a car crash, Thawne took possession of Harrison Wells (Tom Cavanagh)' body and killed the original host. If the Reverse-Flash is from the future, how long has he known Caitlin Snow will become Killer Frost and Cisco will end up as Vibe? Is that why he chose them?

The Flash episode, All-Star Team-Up, airs April 14 at 8pm on CW.
