(S05E05) It's a strange week for Stargate Atlantis. Normally we talk about the episodes of various shows, be they good or bad, based on what was on the screen that week. Behind the scenes goings on occasionally come into play, but rarely to the extent that they do for "Ghost In The Machine." There's a lot of back story to this one, and now that I've seen it I find myself thinking as much about what could have been, as what it is we actually saw. And really, I'm not sure whether or not that's a good thing.

SLIGHT SPOILERS AHEAD! Be aware that I'm just the messenger here.

Remember the time, only a few weeks ago, where a supposed Replicator version of Dr. Elizabeth Weir appeared during the final minute of the Stargate Atlantis episode 'Be All My Sins Remember'd'? And, do you recall the debate that went on here and in the Interwebverse on what that meant? And, didn't it excite you just a bit to see Weir back and being primed for a potential return to the series either late in the fourth season or sometime in the fifth?

Well, as they said in many Shakespearean plays -- tain't happenin'! (That would be Rudy Shakespeare of Pennsauken, New Jersey, that is). That's because Tori Higginson, who portrayed Dr. Weir, has up and quit the show according to an article at the Gateworld website. This announcement especially stinks since Weir was going to be a potential player in a major story arc for season five. That's right! Weir's mysterious appearance at the end of 'Remember'd' was going to be addressed in a future episode which, in turn, was going to become a recurring story arc.

Higginson's reasons for not coming back for another Atlantis season are unknown. A possible reason could have been Weir's removal from the cast list after signing a 6-year contract back in 2004 and relocating to Vancouver, BC. The producers, in what seems like a fairly cold statement, said that they were being quite gracious in keeping on Weir after that happened. Either way, it is unsure at this time if the rogue Replicator storyline, minus Weir, will re-emerge.
