Continuity mistake: In Season 8 - Threads, when Sam is talking to Jack in his backyard (barbecue scene), the back door behind her opens and closes between shots.
Continuity mistake: Jacob Carter repeatedly mentions blending with Selmak 4 years ago, placing it in Series 4 (each season constitutes a year - when Carter leaves the SGC to join Atlantis at the conclusion of season 10, she talks to Teal'c about how they have spent 10 years together). However the blending occurred in Series 2 (6 years ago).
Continuity mistake: The way the C-4 is placed on the blast door changes in various shots.
Continuity mistake: When Hoskin is shot by Carter, the position of his body changes from how we see him to land to the next shot of him when Carter approaches him. At first his arm is extended and his coat lands to cover his gun. In the next shot his ark is by his side and the coat is tucked under but you don't see his gun.
Chosen answer: It's never actually mentioned on the show, though in the 'Continuum' universe, she says she's been with Ba'al for 50 years.
