The Flash Season 1 Episode 8 "Flash vs. Arrow"

Episode 8 of "The Flash" Season 1 will feature two nights of crossover episodes on The CW between "The Flash" and "The Arrow," with Part 1 titled "Flash Vs. Arrow," airing on Dec. 2. Part 2, titled "The Brave and the Bold," is set for Dec. 3.

In the previous episode of "The Flash," it was finally revealed that Dr. Wells (Tom Cavanagh) had been documenting Barry's growing abilities in his "secret room." Barry arrived at a crime scene where he found an electrocuted body, apparently dead. Farooq Gibran (Michael Reventar) attacked Barry by electrocuting him, draining him of his speed.

A team tried to figure out what went wrong and ran tests to find out whether the effects were permanent. Since Barry needed his power back, Wells theorized that all he needed was a "jumpstart," so they tried to use a generator to get his power back. However, the process did not work.

When Caitlin turned on the treadmill, it shocked Barry and sent a billion watts of electricity inside his body. Surprisingly, the shock not only didn't kill him but also brought back his power. Barry was now faster than ever before.

During the crossover, Barry (Grant Gustin) will be thrilled about Oliver (Stephen Amell), Diggle (David Ramsey) and Felicity (Emily Bett Rickards) coming to Central City for an investigation of a case involving a "deadly boomerang." Barry attempts to invite Oliver to team up with him to stop a meta-human named Bivolo (Patrick Sabongui).

Conflict between the two heroes begins when Oliver tells Barry that he "still has a lot to learn." Barry goes out alone and attempts to stop Bivolo without Oliver's help. The partnership doesn't go as smoothly as they have expected. Bivolo then infects Barry, putting everyone in danger. This leaves the Arrow as the only one who can stop The Flash, who is now on a rage.

Barry Allen was just 11 years old when his mother was killed in a bizarre and terrifying incident and his father was falsely convicted of the murder. With his life changed forever by the tragedy, Barry was taken in and raised by Detective Joe West, the father of Barry’s best friend, Iris. 

Now, Barry has become a brilliant, driven and endearingly geeky CSI investigator, whose determination to uncover the truth about his mother’s strange death leads him to follow up on every unexplained urban legend and scientific advancement that comes along. 

Barry’s latest obsession is a cutting edge particle accelerator, created by visionary physicist Harrison Wells and his S.T.A.R. Labs team, who claim that this invention will bring about unimaginable advancements in power and medicine. 

However, something goes horribly wrong during the public unveiling, and when the devastating explosion causes a freak storm, many lives are lost and Barry is struck by lightning. After nine months in a coma, Barry awakens to find his life has changed once again – the accident has given him the power of super speed, granting him the ability to move through Central City like an unseen guardian angel.
