After a short hiatus, fans will love the upcoming episode of "The Flash" because team Arrow makes an appearance and "The Walking Dead" actress Emily Kinney guest stars as the episode's antagonist.

In episode 18 aptly named "All Star Team Up", Felicity Smoak and Ray Palmer visit S.T.A.R Labs because Ray needs help with his Atom suit, reports TVLine. While in Central City, Felicity and Ray serve as backup as a new threat engulfs the city. A new meta-human known as the Bug-Eye Bandit unleashes a swarm of robotic bees on the city to target her former co-workers and only Barry can prevent her from doing harm. The Bug-Eye Bandit's real name is Brie Larvin.

However, another TVLine report suggests that Arrow, the Flash and Atom will be fighting Harrison Wells' Reverse Flash after dealing with the meta-human threat. He will prove to a problematic foe and one that needs a team of superheroes to deal with. The report also teases that Barry Allen will give Eddie quiet a beating and someone in the show will meet a potentially deadly fall. Who can this person be?

The promotional clip shows Barry proclaiming he will take down Reverse Flash for good. Another interesting aspect of the episode will be that Barry, Felicity, Ray and Iris go on an awkward double-date. This will certainly be interesting to watch given Iris and Barry's history and the fact that he revealed his true identity to Eddie. Barry told Eddie he is the Flash in a previous episode in order to seek his assistance for protecting Iris against Dr. Wells.

Devout viewers of "The Flash" should enjoy the show as much as they can since the season finale airs in May. "All Star Team Up" airs on Tuesday, April 14 at 8 p.m. ET on CW.
