There have been no official indications that Aquaman is a part of The CW's ever-expanding Arrowverse, but this deleted scene from the pilot episode of "The Flash" indicates that Superman and Aquaman have at least been considered.
In the cut scene, a pre-powers Barry Allen (Grant Gustin) discusses reports of a man who can bend steel with his bare hands in Starling City, and a man who can talk to fish in Amnesty Bay. Dismissed as urban legends by Det. Joe West (Jesse L. Martin), the conversation quickly turns to Barry's mother's death -- and the fateful STAR Labs particle accelerator experiment that will give Barry his super speed.
"The Flash" returns to The CW on Tuesday, Oct. 6.
