Since there’s so much unfinished business…
“Dead Stop” sequel: Months later, Archer finally remembers to make Trip and Malcolm serve an extended time-out in their quarters. Meanwhile, Phlox discovers that Travis should have gone through decon (he’s the only one who hasn’t been in there yet–besides Phlox himself, not that I’m looking forward to it).
“Marauders” sequel (this is one I’m actually serious about): In need of deuterium, Archer and company return to the mining colony planet–only to find everyone dead and the place burned to the ground by the vengeful Klingons. This is one major incident that will bring about the drafting of the Prime Directive.
