It was released a while back that this season of "Arrow" we would see The Flash introduced before given his own show next season. We found out a few weeks back that Grant Gustin will be playing The Flash an now we have our first look at him.
We have also found out today that, CW are going old school with their introduction of The Flash. Usually the pilot will be a back-door pilot in which the first show "Arrow" would have a whole episode dedicated to the back story of the new character/show, however CW are going the more traditional route an The Flash will have its own pilot in the next television season. We are set to see Gustins Flash in Decemeber in an episode titled "The Scientist" but if you can't wait here he is. The episode synopsis is below read if you want, if you don't want a spoiler ignore the bold italic text 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 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 takes a liking to Barry, which doesn’t go unnoticed by Oliver. Sin (guest star Bex Taylor-Klaus) asks Roy for help when a friend of hers goes missing. Roy is surprised when Thea 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."
