Insomniacs' special!

Thanks to everyone for providing the clues that I needed to get out of my situation in the last part (or rather, shouldn't have needed because all it took was going down an incredibly obvious passage) - in this episode, we have a lecture on observation, a lot of progress without a lot of big events (but some big explosions), and a strange obsession with toasters (I missed a dose of thyroid medication today). It's incredible even to me that I have absolutely no idea what I'm going to say in these before I do them.

The episode ends with me stuck in completely the opposite way from how I started it, free and wandering all over the cave system trying to remember where I've seen yellow doors or things that look like they might need to be cooled down a bit. I've made a couple of laps of the game, but haven't yet found the one that'll actually allow me to progress.
