- "According to Index archives, Nash has been on S.H.I.E.L.D.'s radar for about six years. Originally a bond trader in Canada doing very well for himself. Then the Canadian government recruited him to a secret Department H-type program."
"They were looking for people with psychic abilities."
"Specifically people who could control human behavior."
- ―Skye and Melinda May
Department H is a secret organization within the Canadian government that lists people with psychic abilities, specifically who can control human behavior.
Once, Department H recruited Thomas Nash, due to his alleged psychic abilities, despite never proving he could affect people's behavior, just occasionally predict it.
- In the comics, Department H is a branch of the Canadian government that sanctioned, supported, and monitored all the superhuman activity in Canada. It also oversaw the superhuman team Alpha Flight.
