Barry Allen — the Century City Police forensic scientist destined to become DC Comics superhero The Flash — makes his “Arrow” debut on this Wednesday’s episode, “The Scientist,” as played by actor Grant Gustin.
In this clip, a curious, non-powered Barry quizzes Felicity Smoak (Emily Bett Rickards) on her experiences with “the vigilante” — main character Oliver Queen (Stephen Amell). Gustin will appear in two episodes of “Arrow;” this week’s, plus “Three Ghosts,” airing Dec. 11.
“He’s fun to play. He’s likeable. I would be his friend,” Gustin said during a press event Monday at The CW’s Burbank headquarters. “I haven’t had the opportunity to play a character that I would actually enjoy spending time with.”
