I feel as if we're missing the BEST original character to be making it's triumphant return, sure the trailer didn't give the role away, but hidden away in a set photo…

It certainly seems like she's taken the role of Night Nurse, who does treat a whole bunch of superheroes across the Marvel 'verse. You'd think she'd be hired by SHIELD at some point in the MCU and give her more than what she can borrow from her job.

Well Madame Gao near the end sure suggested more ninja mystical insanity, if the fan theories are correct with K'un Lun.

The Unknown Martial Artist is all but confirmed as Stone; Stick's *other* top pupil. Now if the show is going along with the comics, this guy is almost indestructible when defending. …So we'll see in season 2 if Stick and Stone can… break Matt's bones… *sighs*

From what I've seen Paul's twitter, Jill Talley was definitely there for rehearsals so either she's just hanging out or she's back in the gang.

I really want to see Turk try to use the Stilt Man get-up just to immediately fail. He's trying to pull it off a table as DD's coming after him and one of the legs just launches him into a wall. DD checks to see if he's alive and advises him to stick with guns.

He's literally just the accountant, which even for the Mafia is still just paperwork. Why wouldn't he sass everyone he works with as if they work in an office?

Yes, but he also does a pretty piss poor job on that crooked detective, who then goes on to slip DD yet more information he needs to crack down on Fisk before dying. It'd be neat if it was Bullseye but that really isn't the best first impression of his abilities.
