No Zane, no Grace. Adama almost made up for it, though.
I loved seeing the characters in "Simpsons" form.
The Warehouse 13 episode-- well, I enjoyed it for the character stuff. But apparently removing Pete from the timeline would affect nothing at all except for the personal histories of Myka, Artie and Claudia. After all the times Artie and Pete's team have prevented disaster: Now McPherson was in charge of the warehouse all this time and history turns out exactly the same-- really?
