Will the solarium GOOD ending ever be cleared?

[SL the Pyro]

This is a collar key.
Unlocks places you'd otherwise need a bone to pick. Proof that you are an awful human being.
It is a tiny item.

It was inside my skull. I was the only one on, I was the unique.

Valterak came in and cut my skull out and cut the skull open.

Still no idea how to FIND the unique when you have like 40 people but ehhh we know the key is there.

The key is pretty gruesome looking.

Turns out the Automaton won't take the collar key in its post-skull-removal state. You have to clean it up somehow. (I know how, but it's very blatantly obvious and I shouldn't need to give a hint.)

This might be a silly idea, but if the Hydroponics Guide is the key to decoding the cypher, well...

I tried to feed the book to the Automaton thinking the same thing, but no, he wouldn't take it. (Though I didn't necessarily try during the "holds its hand out as if reading" phase...)
