Poor Eloise the rat...
Some time back, I posted a question about her on thefuselage.com for script coordinator Gregg Nations:
A lot of viewers, myself included, are confused about what happened to Eloise the [rat]. Did Daniel ever actually teach her the maze -- e.g., during the period that Desmond was unconscious? Or did Eloise die before Dan had the chance to do so?
I'm pleased to report that Gregg has answered my question:
Faraday did tell Eloise the rat the maze, we just didn't see it. Then of course she died. Very sad...Very sad indeed! But also telling because it confirms that Daniel avoided logical paradox by completing the causal loop. I had begun to wonder if the deaths by hemorrhage were the universe nipping nascent paradoxes in the bud. The test of this hypothesis was whether Daniel ever actually taught Eloise the maze. If he had not, it might indicate that her death was indeed the universe course correcting.
Gregg's gracious reply confirms that Daniel did so, apparently falsifying this hypothesis. It thus seems likely that Eloise, like Minkowski and Charlotte, died from hemorrhages that resulted from them being unstuck in time. Ago gratias tibi,* Gregg!
