Complete Vision's story, which I'd imagine is his death... again.
Wanda finding closure with whatever Vision's outcome is, the kids' outcome, and setting up for Strange 2
What being the Scarlett Witch means and why Wanda? (aka if she's a mutant or something)
Set Monica up for CM 2 while moving up or wrapping up her issues with Wanda and SWORD (and maybe why Monica's got her powers and others didn't, is she a mutant, too?)
If the kids are real
Fietro's reveal
SWORD/Hayward's plans
Expand Agatha's motivation and wrap it up.
.... all while moving the MCU forward
They also should probably explain a few other things, including how Ep 7 said it was Agatha all along, but Ep 8 revealed it wasn't ALL Agatha. How did she get in? How did she know before everyone else?
Not to mention, they still haven't said who the important witness was that SWORD was trying to recover.
And while we know why Wanda created a sitcom reality, why the hell was it broadcasted as a sitcom?
Finally, if that Engineer that Monica knows is actually a somebody. It seems now that the person Bettany was teasing was "himself" - which was a cheap move if that's the case.
