I'm not disagreeing that she couldn't pull it off, but I doubt Black Siren escaped without any indication. Sounds like something Team Flash would call Team Arrow about, given the circumstances. And the evil doppelganger thing is kinda played out on the CW, so hopefully this isn't that. But kinda hard to know for sure, given Katie's universe regular status.
