Editing Bennett Knox (section)

== Relationships ==
===[[Melanie Cavill]]===
Melanie and Bennett are shown to have developed a romantic relationship and she trusts Bennett implicitly to carry out tasks for her. However, Bennett later betrays Melanie when ''[[Big Alice]]'' arrives. After Melanie reboards the train and they are reunited, the two share a hug. Bennett later explains to [[Andre Layton]] that they came up through Wilford's Engineering program together and stuck together despite Wilford's attempts to keep them apart.

After Melanie betrays Layton, Bennett sides with Layton over Melanie, putting them at odds. After Melanie and Layton come to a peaceful resolution, Bennett reunites with Melanie and agrees to stay on ''Snowpiercer'' with her after Melanie promises to fully commit herself to their relationship.

===[[Javier De La Torre]]===
Bennett and Javi are shown to be good friends, although they don't often agree. At one point, Javi bitterly notes that he has no choice but to follow Melanie's orders as he isn't sleeping with her like Bennett. Although Javi betrays them when the Folgers take over and Bennett literally throws him out of the Engine, the two men are shown working together afterwards with no animosity, possibly because Javi saved Melanie's life during the revolution.

After Wilford takes control of ''Snowpiercer'', the two men are able to communicate with each other in code over an open radio line with even [[Sykes]], a highly-trained operative, not understanding the true meaning of their messages. When Javi comes under siege, perhaps understanding what is likely to happen to his friend, Bennett gets visibly emotional and reassures Javi, calling him "a hell of an engineer."

===[[Miles]]===
At first, Bennett appears to have a good working relationship with [[Miles]], the young Tailie fast-tracked as an Engineer Apprentice. However, after learning that Miles helped spark the revolution by informing [[LJ Folger]] of the truth, Bennett goes so far as to threaten Miles in his anger, although he doesn't seem to entirely blame Miles for his actions. When Miles tells Bennett that he helped free the Tail, Bennett states that Miles isn't a soldier but a tragic child.

As they are trapped together in the Engine, Bennett's attitude towards Miles quickly softens and he begins answering Miles' questions, including explaining why the Tail is kept so cold and dark. When Melanie contacts them with a plan, Miles and Bennett work seamlessly together to drive the train and disconnect seven cars to kill the enemy army. After they succeed, Bennett and Miles hug and Bennett congratulates Miles, addressing him as Engineer.

===[[Joseph Wilford]]===
Not much is known about Bennett's relationship with the real Mr. Wilford aside from him thinking that they need to surrender due to the dire state of the train. Notably, Mr. Wilford actually remembers Bennett while talking with Melanie, calling him Ben and appearing to be aware of Melanie's relationship with and favoritism towards Bennett. It's revealed that Bennett was actually in on the plot to steal ''Snowpiercer'' and urged Melanie to leave Wilford behind because Bennett knew just how bad Wilford was.

When Melanie tried to take Bennett with her aboard ''Big Alice'', Wilford refused, calling it "a Ben-free zone." Bennett later tells [[Andre Layton]] that due to Wilford's need for control, he had always tried to keep Bennett and Melanie apart while they were in Wilford's engineering program, but they had refused to allow him to win which is at least part of the reason why Wilford doesn't want Bennett on his train. Bennett is concerned enough about Wilford's plans that he forms an alliance with Layton to keep the train safe together in Melanie's absence.

===[[Andre Layton]]===
While Bennett and Layton at first don't have much interaction, they start to get to know each other after Layton takes control of ''[[Snowpiercer]]'' and ''[[Big Alice]]'' shows up. At first, Bennett is opposed to the idea of reporting to Layton, but after the arrival of ''Big Alice'', begins working closely with him. The two men soon form a mutual alliance out of their hatred for Wilford and need to keep the train safe in Melanie's absence. Bennett quickly becomes one of Layton's most trusted advisors and friends, often taking part in meetings regarding train business and keeping each other apprised of situations. In this respect, Bennett's loyalty to Layton is similar to his absolute loyalty to Melanie after she took control of the train. Even after Wilford takes control of ''Snowpiercer'', Bennett retains his loyalty to Layton and Melanie, happily taking the chance to betray Wilford and help his friends.

After the discovery of Melanie's apparent death and the recovery of her data, Bennett remains loyal to Layton on the [[Pirate Train]], looking to him for direction along with the rest of Layton's crew. Over their six months together on the Pirate Train, Bennett and Layton become close friends.

When Layton is put into a coma from [[Pike]]'s attempts to assassinate him, Bennett is one of his friends who visits the unconscious Layton and he is visibly deeply worried for him. Forced to return to the Engine, Bennett asks [[Doctor Pelton]] to keep him updated on Layton's condition.

When Layton and Melanie are at odds again, Bennett chooses to side with Layton over Melanie. After a peaceful resolution is reached, Bennett stays on ''Snowpiercer'' with Melanie rather than joining Layton on ''[[Big Alice]]'', parting on good terms with his friend.
