it would be a whole lot better if in an after scene, they showed Agent May meeting Strange and handing him the Darkhold, although I don't think we've seen the last of the book on the show. Unless they do one of those cheap things where all of a sudden, one of the characters shows up with it and say's "I had to make a stop somewhere to pick this up". I doubt it though.

Dr. Strange was the key to getting the Midnight Sons books up and running. These included characters such as Blade, Ghost Rider, the Nightstalkers, as well as the Darkhold book and a team called the Darkhold redeemers which were trying to neutralize it.
In that sense, this season sort of ties in with Dr. Strange already. It would be interesting to see if say the after credit scene showed Strange meeting up with Ghost Rider or something, but that I'm afraid is a little too much to ask.
I'm so uglythat's ok 'cause so are you.

it does.. it's the Darkhold in the comics Dr Strange used it to eliminate the vampires of earth except for one.
