[SPOILER] Who’s who? Penumbra narrative puzzle

[Black Rabbit]

my theory was (right after the game ended) that red was philip and that he became red after black plague or something...like a paradox? maybe red is a tuurngait lust like clarence and was there to punish those who trick that entity? so he entered philip as well and so that they don't do the same mistake and keep their existence hidden this time they also try to burn the character from requiem with philip who was by then consumed by red who was actually a tuurngait? remember when clarence wanted the philip to die so that he could return to the greater entity? and that red said release me from this "mortal coil" maybe he was also a tuurngait trapped in a miner...plus his voice was weird...just like that doctor who needs a saw in black plague...you know the infected ones talk funny and fast
