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.
