The CW has just released the first promo for episode 2.08 of their hit series “Arrow,” which will serve as a two part mid-season finale before the show returns in 2014. What makes the episode extra special though is that it features the series debut of Grant Gustin as Barry Allen, who will later go on to become The Flash in his own potential spin-off series. Titled “The Scientist,” the episode is described as follows:
“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.”
