Stargate Atlantis/Recap/S04/E09 Miller's Crossing

"You figure four masked men with guns broke in here to steal her secret apple dumpling recipe? Jealous neighbor maybe?"

- Kaleb Miller explains at length why this is all McKay's fault.

Tropes:

 * The Atoner: Wallace.
 * Buy Them Off: McKay's imposed pennance for the events of the episode includes eating vegitarian food without complaining, reading his neice extra bedtime stories, and buying Jeannie's family a Prius. May be a subversion, since, rather than actually being insincere, he's doing all this to hide the fact he actually attempted the Redemption Equals Death route (but was preempted).
 * Convenient Coma: Jeannie is placed into a medical coma while the others hurry to find a solution.
 * Driven to Suicide / Heroic Sacrifice: McKay offers to feed himself to the Wraith to save Jeannie, but Sheppard makes Wallace do it instead.
 * Dynamic Entry: Comically averted. McKay attempts to kick down the door, but Agent Barret preempts him by calmly opening it.
 * Empty Shell: Sharon's fate after the nanites shut her down for repairs.
 * Gone Horribly Right: The nanites, which work too well, repairing not only the cancer but every defect they can find, regardless of the effect on the host.
 * Idiot Ball: So they figure Todd the Wraith is the only one who can save Jeannie. Fair enough - but whose bright idea is it to bring him to Earth, rather than just taking her to Atlantis?
 * Offstage Waiting Room: Ronon gets briefly stuck in one.
 * Redemption Equals Death: How Sheppard sells Wallace on the idea of feeding himself to a Wraith.
 * We Could Have Avoided All This
 * What the Hell Hero: McKay gives Sheppard a very mild version at the end of the episode, rendered more unusual by ending it with "thanks."
