Warning: this is for anyone who has seen the latest Supergirl episode on CBS, if you have, please keep reading, if not, stop here to avoid spoilers

So, if you read my warning, and you HAVE seen the latest Supergirl, where Siobhan, Cat's now-fired assistant has that sonic screech thing going on, I think we can all agree on one thing:

Siobhan either IS Black Canary (look her up if you don't know who that is, she's in the Justice League), or her MOM, who she said was cheated on by Siobhan's dad, is Black Canary!

Comment if you agree!

(If you still don't know who Siobhan is, I posted her picture on the top⬆️⬆️⬆️)
