Scully: Mulder?
Mulder: Over here.
Scully: What is it?
Mulder: Diazepam. She used them to sleep.
Scully: Is there a note?
Mulder: No. She called when I was in California. She wanted to talk, but, uh... I never called her back.
Scully: Mulder...
Mulder: I didn't... Why would she do this? It just doesn't make any sense.
Scully: We never truly know why.

No One Shoots At Santa Claus
29 May 2007 | by (Roy, Utah) – See all my reviews

Sein Und Zeit begins the story that will finally reveal the truth to us about the abduction of Mulder's sister, Samantha. It feels like the writers and producers of the show were trying to wrap the main story lines up, maybe in anticipation of the series ending. In season six, the syndicate is all killed by the faceless rebels, and in this two-parter the story of Mulder's sister is wrapped up. These two story lines were the impetus for Mulder's quest. After 'Closure', the show heads in a different direction. An odd thing I noticed in the beginning of the episode is that Mrs. LaPierre has a Hollywood video in her dresser drawer. That has got to be overdue! She'll surely forget to return it if it's left in there. I found it disturbing that FBI agents had a pool going on whether or not Amber LaPierre was dead. How sick. A moment of cinematography I liked is when the TV at Ed Truelove's place is on the news. The camera closes in on the TV and when it pulls out, we are at the FBI watching the same thing, no longer in Truelove's place. David Duchovny's acting is so strong in these episodes about his sister. It is second to none. It's quite interesting that it is Scully that discovers the "74" clue to find Santa's North Pole Village, and not Mulder. Finally, X-Files characters are normally named after friends and families of the writers of the episodes and don't carry any significance. The character Ed Truelove, however, does bear significance as his name is an oxymoron, meaning he believes he has true love for these little girls he kidnaps, while in reality it is nowhere near true love. The ending scene of the unmarked graves is poignant as we are left wondering if maybe Mulder's sister is buried here. Sein Und Zeit is a poignant episode with excellent acting by David Duchovny leading up to moment of truth about his sister in 'Closure'.
