Now that we’re getting into the real meat of Hell on Wheels, (and moving on to other topics,) I find myself wondering exactly where the story can go beyond this first season. Naturally, a lot will change between now and the season finale, but there are still questions that should be addressed if we assume the length of some arcs.
Promotional material for the show highlights only Cullen and Elam. Both have guns, both are dressed in a similar manner. A partnership for the two seems very likely, and barring other contractual obligations or conflicts, I would be very surprised if either left the show after this first season. That said, we can recognize the difference between the two in the current narrative, so the show must resolve how these two end up in “equal standing.”
The action itself will drift away from Hell on Wheels, simply because the railroad has a destination to be built to, and Cullen has a piece of his vengeance to attend to in the setting. Both of these are shaping up to be season-long arcs, concluded in the finale, because to take any longer would almost necessarily stretch these two goals to be second season arcs. Cullen killing his target and somehow sticking with Hell on Wheels (assuming the railroad isn’t finished) would be a piece of narrative acrobatics, knowing as we do that Cullen’s target is a man of some prominence within the railroad town.
The advertising and title suggest to me that after this season, Cullen and Elam will become “hell on wheels” (well, horses,) as Cullen’s quest takes them away from the railroad and on to more varied locales. Then again, my theory is sunk by the rest of the ensemble cast: they can’t all travel wherever Cullen goes, and I don’t think a show like this can maintain scattered POV.
