There are a number of dangling plots from Priest's small body of work as writer at Marvel comics that I would like him to be able to follow up on.
T'Challa, the Black Panther, developed an incurable brain aneurysm and witnessed the death of his long suffering, yet joyful, future self at the hands of one of his rival chieftains, and thus fell into a paralyzing depression as Killmonger still technically retained the title of chieftain of the Black Panther cult.
In the meantime, Officer Kevin 'Kasper' Cole briefly wore the Black Panther costume in order to confront the powerful 66 Bridges gang, which is apparently run by his own father with another son, Triage, a possible half-brother Kasper doesn't know to exist, both Africans who maintain a strong connection with their tribal custom and heritage.
Some time later, the Falcon clashed head-on with elements of the U.S. Intelligence community, increasingly entering a territory where the conventional definition of heroism couldn't apply anymore and questioning his own identity in the process.
Which, come to think of it, is what all of Priest's work is about, bridging the gap between the real world and the comic world in a way that uses the medium for all its potential, constantly juxtaposing tragedy and drama with funny and exhilarating plot twists, redefining the scope of super hero fiction the way Claremont, Simonson and Miller did before him.
Only Priest can tie up those loose ends, and I, for one, would like him to have a chance to do so.
