Callum is a minor character in The Last Ones.
Nothing is known about Callum or his life before the outbreak other than that he was imprisoned for an undisclosed crime.
Sometime after the undead outbreak, Callum was among one of the group of inmates who managed to escape prison. When a group, which included Javier Rodriguez and Callum himself, took issue with psychopath Eli Loche's behaviour and him leading the way on the outside, Eli had all of them killed, with only Javier managing to survive.
Callum is mentioned by Eli when he questions Donald about his loyalty. Eli brings him up alongside Richard, Bob and Javier as a reminder of what happens to people who oppose him. Eli was still in the dark regarding Javier's survival.
In this episode, it's revealed that Javier is hunting Eli and his followers in order to seek revenge for the death of Callum and his other friends.
Callum appears in a brief flashback in this episode, where the moment where Eli killed him and his other friends was seen.
Callum appears again as a corpse in the concluding flashback.
This list shows the known victims that Callum has killed:
- Possibly numerous counts of zombies.
- Out of all the main characters, Callum only met Eli and Javier.
- He appears to be the best dressed out of the escaped prison inmates, perhaps hinting that he was a clean and neat person.
