Sorry man, I don't agree with this one. Even if Evelyn was related, she'd have no definite way of knowing, and even if she did that alone is a pretty petty reason to side with Prometheus. This is more about Prometheus playing mind games and turning Oliver's protege against him. He didn't seem to have a problem beating down Evelyn on the train fight.

If Prometheus and Vigilante were the same person then how did they fight each other? Especially since there was no one else watching so they had no point in putting on a show with body doubles like Reverse-Flash did.
