Corrected entry: After Hathor has been burned in her tub, you can see the actress walk offstage to the right of the fire (This is also visible in "Out of Mind" when they remember that part.).
Corrected entry: Hathor is seen leaving the room, when she is supposed to be dead in the bucket of dead parasites. (00:40:40)
Correction: This has been corrected before; she is not dead.
I am rewatching SG1 and I saw a weird movement then I saw some sort of distorted effect and then you see the (assuming) stuntwoman transitioning out of the room. So of course when I watched this I wondered is she still alive, but she does not appear later in the ep, so I assumed it was a goof.
The transition out of the tub does looks odd (intentionally) and then you see someone that looks like they're walking pass the shot. But Hathor does appear later in the episode, she's seen leaving through the Stargate.
Correction: That's not a mistake. It's part of the story. Hathor got out of the tub and walked away to the stargate.
