Continuity mistake: When Raven telekinetically reassembles the broken chime bead necklace, it has about nine beads and is rather tight, but before and after that the necklaces feature about 13 or 14 beads and are wide enough to fit around the others' necks.
Continuity mistake: Within the timestream, Starfire rips off Warp's vortex regulator with her left hand. She still has it in her hand when she first shields her face with her left arm, but as we see Warp dropping out of the timestream and Starfire following right afterwards, both of her hands are empty.
Continuity mistake: After Warp just barely managed to fend off Nightwing's grenades, he notices Nightwing's shape leaping at him. In that shot, before the scene where Warp sinks into the ground, the socket for his vortex regulator is glowing blue instead of red.
Chosen answer: This is Dick Grayson who will later become Nightwing.
