'Arrow': 'Glee's' Grant Gustin Debuts as Flash (Photo)
Flash, meet Oliver Queen.
The CW released an image Monday of Glee's Grant Gustin making his debut on Arrow as Barry Allen, the man who will become the heroic Flash, in the Dec. 4 episode titled "The Scientist."
When Barry sets foot in Starling City, expect him and Felicity to have a connection -- and others will notice.
"They're really fun, they're really flirty and they're really smart. Both of them are extremely intelligent characters, and I think the audience will enjoy that," Arrow's Emily Bett Rickards told The Hollywood Reporter recently. "It's really interesting to act with someone who's literally as smart as Felicity because I know very few people who are as genius as Felicity is ..."
Stephen Amell, who stars as Oliver Queen/Arrow, described Barry as "a whippersnapper," "enthusiastic" and "incredibly smart" in an October chat with THR. "He's a little naive and his level of enthusiasm and his penchant for problem-solving is something we've seen on the show with Felicity.
Gustin's Flash also will appear in the Dec. 11 episode of Arrow. The character was originally set for a backdoor pilot in episode 20, but will instead film a traditional pilot.
The official synopsis for the episode is 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.
Arrow airs Wednesdays at 8 p.m. on The CW.
