Colin acts as a perfect foil to the scheming and spoiled ways of Logan’s children. He is a man of few words who aspires for little more than he has. He doesn’t try to gain anything from Logan — he just does his job, and this earns him a lot of respect in the old man’s eyes.

“All Logan wants is consistency,” Cox explained, and Colin provides exactly that. “The great thing about Colin — and why he thinks Colin’s probably his best friend — is because he’s never on the make. The relationship is straight. He’s his employer, and he likes being employed by Logan.”

This brings us to their shared moment in the diner. After insisting that Colin is his best friend, Logan presents his own personal philosophies in the form of rhetorical questions and quickly cuts Colin off when he starts to talk about his own background. Jesse Armstrong described this scene as “quite an unreflective man having some feelings of reflection” in a clip following the episode. For Logan, Colin is but a mirror, a wall that he can bounce his own ideas off of. “He asks him a couple of questions, but they’re really rhetorical questions, aren’t they, for him?” Armstrong said. “He’s pretty much decided what he thinks about life after death.”

Logan’s immense wealth and shrewd business tactics have long made him seem invulnerable, save for a few key moments in the series when his health waivers and his impending death is ever-so-jarringly brought back to our attention. His money has made him a giant among p*gmies, as he would put it, but it cannot save even him from the inevitable fate of all life on earth.

“You can keep that at bay for a long time,” Armstrong pointed out, “but no one can keep it at bay forever.”
