The Ending [Reveled][Major Spoilers]

[bertle]

I just want to know what was going on after you did the three tests.

So you're back in the examination room but there's no machine, or table, or computer on the first desk. The vents are shut up and all the doors are locked. Yet the computer you're using to send the email is real?

Nothing else seemed real so why believe the computer was anymore real? Was it possibly the final test and Philip failed it horribly? The walls started disappearing even before he betrayed the hive mind so I have no idea what was going on there but he seemed to be losing his memory as if his brain was just shutting down.

This is whats confusing me, was Philip really back in the room or still stuck in his head, or was he in the real world but partially hallucinating like what Clarence had been doing to him before by removing doors?

It strikes me that with the perception altering abilities of the Tuurngait we can never really know what really happend at the end, or even during the story as there is no clear line between objective reality and hallucination.
