Stargate Atlantis/Recap/S01 E15 Before I Sleep

"It worked."

- first words of 10,000 year old Dr. Weir

Tropes

 * Continuity Cameo: Merlin, who will show up in a later season of SG-1, is on the Lantean high council. Also counts as an Early-Bird Cameo, since at this point the Arthurian plotline hasn't even started on SG-1.
 * Human Popsicle
 * Literary Allusion Title: to Stopping By Woods On A Snowy Evening by Robert Frost
 * Meaningful Name: The Ancient working on time-travel is named Janus - Roman god of Time.
 * Our Time Travel Is Different
 * Ripple-Effect-Proof Memory
 * Shout-Out: Sheppard makes several references to Back to The Future, which McKay does his best to quash.
 * The Slow Path: Weir's return to Atlantis - a bit of a subversion, however, in that she had to leave stasis every once in awhile to rotate her power source and make sure everything was working.
 * Time and Relative Dimensions In Space: This episode uses the "you end up in outer space" model - which is curious, because the SG-1 episode using the same technology doesn't.
