Titans Season 2 Finale: 10 Major Questions We're Left With After 'Nightwing'

Cadmus sure knew how to make an impression in a short space of time. After a slight tease in the Season 1 finale tease, the villainous organization wasn't officially introduced until half way through the second offering. But it only took a few appearances for them to ascend to 'major threat' level. The person responsible for this was none other than Lex Luthor's right-hand woman Mercy Graves.

Thankfully, the Titans were able to stop Graves' barbaric plan to turn Cadmus' own creation, Conner, into a mindless weapon that could be sold to the highest bidder, when they got through to both him and Gar (who had also been kidnapped and brainwashed by her). And in the end, there was nowhere to run for Mercy.

But does her defeat mean that Cadmus has closed for business, or will the man behind it all finally make his presence felt on the show? Remember, she did received a call from Mr. Luthor right as things went south for her team, so naturally, our interest is piqued. Could the iconic Superman villain cross paths with the Titans in Season 3?
