My hope is that Jean and Scott have split up when the show begins, allowing for the Scott-Emma romance. That would definitely make heads explode, but it’s been a big part of the past twenty years since Morrison so I’m sure it’s got to show up at some point in some form or fashion.
Hell, I’d love to see them adapt some of Morrison’s New X-men run for that matter. Cassandra Nova, the expanding of the school to more than just a handful of students, Fantomex and Weapon Plus, etc. Bring all that stuff on!
