CW To Shoot Stand-alone Pilot For Flash, Arrow Spinoff

What do you think about Grant Gustin as Flash? Gustin will debut as Barry Allen on "Arrow" in season two. Allen is the alter ego of DC Comics superhero Flash.

He will appear in episode 8 "The Scientist" on Dec. 4 and episode 9 "Three Ghosts" on Dec. 11.

The episodes will are a two-part mid-season finale. That producers claim will change everything, "... in a flash."

Very clever.

According to The Hollywood Reporter, "The character was originally set for a backdoor pilot in episode 20, but will instead film a traditional pilot."

Read the synopsis of episode 8 below,

A seemingly impossible robbery at Queen Consolidated's Applied Sciences Division brings Central City police scientist Barry Allen (guest star Grant Gustin) to town. Citing a similar case back home, Barry offers to help Oliver (Stephen Amell) and team with the investigation. Oliver senses there is more to Barry than meets the eye, but he's distracted by the similarities between this current case and something that happened on the island. Meanwhile, Felicity (Emily Bett Rickards) takes a liking to Barry, which doesn't go unnoticed by Oliver. Sin (guest star Bex Taylor-Klaus) asks Roy (Colton Haynes) for help when a friend of hers goes missing. Roy is surprised when Thea (Willa Holland) not only encourages him to help, but joins the search. Unfortunately, Sin's friend is connected to Brother Blood (guest star Kevin Alejandro), and their search ultimately gets one of them seriously injured.
