Corrected entry: When Dr. Fraiser has just told Carter about the rowboat and Carter leaves singing "Row your boat" the monitors on the wall next to Dr. Frasier show the other SG-1 members. The sticker that says "Jackson" is under O'Neill's monitor and "O'Neill" is under Dr. Jackson's monitor.
Corrected entry: When SG-1 is getting ready to leave the planet, Sam pushes the first symbol on the DHD, and then they stop to kill the possessed man. When Sam goes back to the DHD, you can see that the first symbol is still lit, and then you hear her push 8 more for a total of 9. Only 7 are required to dial a Stargate.
Corrected entry: The Carters decide that Alternate Carter is suffering from the entropic cascade failure because of the "increased entropy generated by both of [them] existing in the same reality." It's further explained that Kawalsky didn't get the cascade failure because this universe's Kawasky is dead. Even so, Kawalsky's matter still exists. Shouldn't he also be generating increased entropy, and therefore be suffering from entropic cascade failure as well?
Corrected entry: When SG1 and Nick are walking along the bridge inside the cavern near the end where Daniel is 'invisible', they are all evenly spaced out with Daniel in the middle and Nick at the front. But if he was invisible, then the person behind him would have not left so big a gap, it would have been half the size.Craig Bryant
Corrected entry: When Carter is taking out the marker in the blood left by Jallinar, she uses a centrifuge. That will work great except that she didn't balance it by putting a test-tube or something else (water will work fine) on the other side. It's possible that she goofed up, Fraiser was walking her through it and everything, but I doubt it. If she did just have a slip of the memory, the centrifuge would only shake and maybe fall off the table, we don't see if it did or not.
