There is a huge story waiting to be told (that probably never will) about 'mutant self-loathing' and people like Jay Guthrie, who don't *want* to be mutants, and whether or not they should have the right to 'transition' back to being humans, like they were for the first dozen or so years of their lives.
Plus a whole lotta story about the other Guthries (who aren't Sam). What's Paige up to? What's Melody's actual power ('flight *aura*' sounds more interesting than just 'flight', can she extend it to others and do the Peter Pan thing where all her friends can fly with her?)? What's Jeb's power (not-burny blue lightning-fire, apparently, but that could have been a telepathic effect or a light-illusion, for all I know, not some sort of cold electrical plasma!)? Do the other five kids have powers? Will Elizabeth ever become Amazon, a size-changer like in the Age of Apocalypse? Will the mysterious tenth sibling ever even get a *name?*
Does Lucinda Guthrie (their mom) have the mutant power to support and raise and feed 10 kids as a single parent without going totally mental or suffering a complete mental and physical collapse? Does she get any sort of financial support from Xavier, Paige, Sam, etc.?
Was their 'dead father' secretly Nathaniel Essex, in one of his many guises?
