Couple of Questions (Spoilers)

[MissingNo.]

I was curious as to a few things that came up over the course of the game. Wanted to know what other players thought since no real answers are really given.

In Overture, inside the large power room we see a giant shaft. Now, Phil makes the note that this shaft seems to be uneven like it was carved from hand. I think we are meant to assume it was one of the worms--but the question is where did the worm go? There isn't really an exit to the shaft. So, why was he there?

My other question is do you guys think that Phillip looks like one of the Tuurngait by the end of the game? We don't really see many mirrors, though I remember hearing the doctor lady stating that Phillip looked worse everytime she saw him. So, are we hideously mutated by the end of the game?
