[SPOILER] Who’s who? Penumbra narrative puzzle

[Mr. X]

Woah that was one hell of a text! I had to read it 10 times to remember what you wrote lol
I thought that in the ending of requiem where you enter the door, Phillip is back in the cabin on the boat and dreamt everything that has happened in all the games? Or was he like, teleported back there by the Tuurngait? For the other Red ending, i have no theories more than that Phillip dies and is never coming back :3
