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.
