The CW and DC Entertainment have released a new promo and Producer’s Preview for this week’s all-new episode of Arrow. This week’s episode, “The Scientist,” is the first of a two-part mid-season finale and the first episode featuring Barry Allen (guest star Grant Gustin), aka The Flash.
In the next episode, a seemingly impossible robbery at Queen Consolidated’s Applied Sciences Division brings Central City police scientist Barry Allen 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.
You can check out below a new 30-second promo for the episode, along with a Producer’s Preview with Executive Producer, Andrew Kreisberg. The first part of the Arrow 2-part midseason finale premieres on Wednesday, December 4th at 8pm on The CW.
