So what about Craig Geraghty/Ringmaster? What are they going to do with him? He listed for only tow shows so it's doubtful he'll be the main villein. And with Jessica Jones having spent an entire season with Kilgrave, mind control needs a little rest.
I doubt it is the classic Ringmaster as he isn't an Iron Fist rogue and the Netflix series is a bit too grounded for a guy like that. It is probably either a random ringleader who might show up in a circus scene or something (maybe even one of the inmates in the asylum who thinks he's in a circus), or he is the ringleader of a group of criminals or something.
Very likely. There is a MMA Bouncer or something in the credits. I'm guessing Danny or maybe one of his villains steps into a MMA ring to do a little damage.
