Jonas Quinn

Jonas Quinn is a fictional character in the Canadian-American television series Stargate SG-1, a science fiction show about a military team exploring the galaxy via a network of alien transportation devices. Played by Corin Nemec, Jonas is introduced in the season 5 episode "Meridian." Jonas fills Daniel Jackson's empty spot on the SG-1 team in season 6 and the beginning of season 7, and last appears in the mid-season 7 episode "Fallout".

Nemec's character replaced Daniel Jackson (portrayed by Michael Shanks) during season 6 after Shanks had left the show amid controversy after season 5. The producers based Jonas's motivation to join Stargate Command on his momentary reluctance to actively prevent Daniel's death, and his feelings of responsibility afterwards. Jonas was slowly integrated into the story in a prolonged transition stage over the first half of season 6. Nemec was open to continue playing Jonas Quinn after season 6, but a new contract was reached with Michael Shanks for Daniel to return in season 7. The role of Jonas was reduced to recurring status in season 7.
