Flash vs. Arrow

"Okay. we'll help you catch your bad guy. Great, "Metahuman"! I'm not calling him that, Barry. Partner? Partner."

- Oliver Queen and Barry Allen

Synopsis
Barry is thrilled when Oliver, Felicity and Diggle come to Central City to investigate a case involving a deadly boomerang. Excited about teaming up with his friend, Barry asks Oliver if he'd like to help him stop Roy Bivolo, the meta-human Barry is currently tracking. Bivolo causes people to lose control of their emotions and has been using that skill to rob banks. Unfortunately, the superhero partnership doesn't go as smoothly as Barry expected. When Oliver tells Barry he still has a lot to learn, Barry sets out to prove him wrong by attempting to stop Bivolo alone. However, when Bivolo infects Barry and sets him on a rage rampage, everyone is in danger, and the only one who can stop him is the Arrow. Meanwhile, Iris is furious when Eddie tries to get a task force to stop The Flash. Joe and Dr. Wells agree The Arrow is a bad influence on Barry and Caitlin and Cisco deal with a new team in S.T.A.R. Labs.
