Robin, Beast Boy and others in “Unfinished Business”

Is it possible he might actually be telling the truth? Could he really be from the future?

Beast Boy

Tell us something we don't know yet, when do I become leader of the team? When do I join the Justice League? When do I get my own reality series?

Impulse

Sorry BB. Never was the best history student. Besides, we can't risk altering the time stream. We do that and we're all feeling the mode.

Beast Boy

And the mode...would be bad?
