I posted before my intial thoughts of the episode “Grey Matters”, but it will never be complete without an in-depth look at the episode, try to find some easter eggs and clues that could help us answer some of the questions. I will also try to convey my own theories in this post.
1. Who is Thomas Jerome Newton?

His name seems to be taken from a sci-fi film called The Man Who Fell to Earth. Thomas Newton, in the film, is a humanoid alien who came to Earth to bring water back to his home planet, which is experiencing a drought. Could the drought be The Blight in the Fringe world? I wonder if Fringe’s Netwon would be needing to get something from our planet to send over to the other world. But it seems to me that is not the case, as the shapeshifters could just easily get what they needed and request an extraction from the alterworld through the typewriter used in the earlier episodes. The only reason left is that Newton wants to open the portal in order to allow the rest of the aliens come in and invade the Earth.
