What was the deal with Ross? (spoilers; every post a spoiler)

[Abion47]

The current popular theory is that Ross, and similarly the Jiangshi, doesn't actually teleport, but instead gives out pulses of electromagnetism. Simon is a robot, so these pulses temporarily disable him, and after a few moments, he regains his consciousness. This is similar to what happens to Catherine when she is plugged/unplugged from the terminals, and like Catherine, Simon has no memory or sense of time passing while he is inactive, so to him, anything that moved around during that time period would have looked like it teleported.

I've been having a looooong think about this and I have come to the conclusion, Ross may not be real ATALL. Think for just a second, he's nothing but flesh held together with some W.A.U. cicuitry and he JUMPED down into the abyss "where you can be compacted to the size of a small can"....so my question is, why is he not compacted down to the size of a small can? XD

Im starting to think the sucker's all in your head

Except when he jumped onto the climber, Catherine saw him too, so Ross seems to be pretty real.
