Personality

Background
Before becoming a mother keeper, Lint was a serial killer using the name "Jack the Ripper". After accidentally killing his wife, Mary, he was caught and put on death row, which gave Jim a chance to turn him into a mother keeper.

He was turned into a mother keeper along with two others, who both ended up dying, leaving him as the only mother keeper until Syal came around.

Mary Kaiser
Mary was Lint's wife when he was a serial killer. Lint killed her by mistake before he was caught.

Ricalna Forde
Lint and Ricalna don't get along as Lint refuses to trust anyone from the rebellion groups. When they first met, Ricalna thought Lint was trying to pick a fight with him and Lint informed him he'd be paying for the damages he had made to Heaven's Tower.

Jim Cleeas
Lint and Jim work together and seemingly get along. However, Lint questions her judgement with trusting Ricalna.

Syal Fineded
When Syal first became a mother keeper, Lint helped her with getting use to things. They get along and Syal breaks up fights between Lint and Ricalna.
