The 5 Best Moments from Hell on Wheels, “Any Sum Within Reason”
(Episode 5.12)

In terms of the development of Cullen Bohannan’s character, “Any Sum Within Reason” works as a really strong revelation for the man and the show. This week Cullen has a determination and a focus within him that he realizes stems from love. But after an entire series spent worrying about whether or not it’s his fault that everyone near him seems to die, Cullen finally comes to terms with the real reason why love has evaded him for so long.
But “Any Sum Within Reason” also brings Hell on Wheels back to its core, finishing off one of the last subplots in the show and setting up for the final two episodes to likely center on finishing the railroad.
Here are the five best moments from last night’s Hell on Wheels.
1. Chang’s Past
In this second half of the season, Hell on Wheels has used flash forwards and flashbacks to elicit sympathy for some of the show’s most morally dubious characters. Thor Gunderson’s past showed him beloved during the war, then forced to do whatever it took to survive from day-to-day. Last week, we saw a flash forward, with Durant dying poor and alone, right after selling what seems to be the last remnant he has from his time at the railroad.
But “Any Sum Within Reason” does the exact opposite with Chang. We flashback to him in China in 1863, buying slaves and bargaining for his own wife, Wai-Ling. When his wife literally stabs Chang in the back and tries to run off, Chang catches her and cuts off her leg as punishment.
While Thor was cruel out of necessity, Chang is cruel out of greed and a desire for power. Witnessing Chang’s past makes him an even more hated character in “Any Sum Within Reason.” Instead of black and white, most of Hell on Wheels’ characters exist in the grey. “Any Sum Within Reason” reassures its audience that Chang is absolutely on the evil side.
2. Contract For Mei/Fong
This meeting between Bohannan and Chang has been in the making since the reveal that Fong is actually a woman by the name of Mei. In this meeting, Cullen tries to civilly earn Mei her freedom, while also admitting the truth about her and her hidden identity. Cullen has tried to hide Fong’s true identity ever since she came clean to him, but at this point, it’s too late for him to avoid the truth from Chang.
This is one of many examples in “Any Sum Within Reason” of Cullen bluntly trying to solve a problem. It’s almost as if he knows the end is coming and doesn’t have time to waste as a result. There’s a sort of exhaustion to Cullen throughout this episode, and especially in his meeting with Chang. He just wants all of the problems and frustrations to be over and will take the easiest route to get to it.
3. Chang’s Search and Cullen’s Revenge
Chang’s search for Mei felt very similar to Thor Gunderson’s search for Naomi at the beginning of this season, but with one distinct difference: Chang can fight. Like, really well. Chang taking on several railroad workers coming at him proved to be one of the finest fight sequences that Hell on Wheels has put together. (Though not as amazing as Common fighting a bear with nothing but his bare hands, also known as the greatest scene in television history.)
