Colonel Jack O'Neill and Teal'c have a recurring case of déja-vu, but it's much worse, they really recall what happened ten hours ago on SG-1's mission to a planet where a device at an altar near its Stargate throws them back in time, yet neither Daniel nor Sam recollect anything so the SGC refuses to believe them, they're tested, found medically okay, the general calls the mission off when Sam feels it might actually be some time-distortion, but that doesn't work. They learn to be more convincing, so they can go to the planet, but there a certain that Malakai proves a problem. Their only hope is to help Daniel decipher the inscriptions on pictures of the altar over many, many time-loops, after Sam helps them make sense of what must be happening; meanwhile Daniel gives them the naughty idea they can get away with pretty much any pranking, as everything reverts to normal unharmed anyhow...

Did You Know?


The book, "Latin for the Novice" that Jack reads when helping to translate the text on the altar is written by Joseph Mallozzi, PhD. Joseph Mallozzi is a writer and producer for Stargate SG-1 (1997). See more »


While playing golf through an active Stargate, Jack asks Teal'c how far away the planet on the other end is; Teal'c says "several billion miles." Given that one light-year is approximately 6 trillion miles, and the closest star-system is 4.5 light-years from Sol, Teal'c is off by several orders of magnitude. This is mostly likely due to Teal'c having no working knowledge of astronomy and thus, he was probably unaware of the true scale of interstellar distances. See more »

Must See
8 July 2010 | by (United States) – See all my reviews

Another one of those episodes that is a must see. Especially if you enjoy the humor of Jack O'neill's (two l's) character. I am not going to write specifics, as I do not want to spoil it. This episode mainly revolves around O'neill and Teal'c, though the rest of the cast is involved. I will just say that this is one of those episodes that really has nothing to do with the main plot of the series, yet as a stand alone episode, it is one of the best. A very entertaining piece that really allows for Richard Dean Anderson's humor to come forth. There are numerous scenes that allow for some great interaction between the stoic Teal'c and the oh so not serious O'neill.
