The Ending [Reveled][Major Spoilers]

[ShardofTruth]

Well, i liked the idea of "think yourself if it was true or not", because the final room was definitely not real in the full sense of "real"... It reminded me of Eternal Sunshine of the Spotless Mind a little - in a genius way of removing some objects from reality (or memory) one by one. What IS interesting to note is that the Hive Mind itself tells Phillip that in the end of the tests he may even has his revenge...
It also reminded me of the whole the Machines vs rogue Agent Smith idea from The Matrix (Reloaded and Revolutions) - Clarence was part of the Hive Mind, but went separated and started thinking differently, with own ambitions. Even the Hive Mind calls him "too human".
Also i still can't understand, why did the hive mind call Howard "too weak". Because he killed himself, or because he failed the tests...

I like this explanation alot.
The Hive tells Phillip may get his revenge. He writes an email, that nobody can obtain, because there is only internal communication possible.
But it's still part of the test and he is held as a prisoner now or lost all his memories etc.
