It opened with a flashback of the Titans when they met Starfire that included Robin (Dick), Speedy, Kid Flash, Bumblebee, and Beast Boy. People assumed Wally was Kid Flash given the line-up, his YJ voice actor having the part, and his personality matching Wally's DCAU/YJ counterparts in the scene.
But James Tucker, who oversaw the animated movies, mentioned the character was actually Barry because they basically thought it would be cool to have him go from the Teen Titans to the League. He also mentioned they had no intentions of ever using Wally in the universe -- though Wallace had a silent cameo in the next film that ended the universe.
