anyone notice the five portraits in the first room you unlock upstairs. it has the four characters you play as and the fifth on is just a silhouette, if you hold X to them the character you play as has dialog for it. Takeo says "maybe what was is now no more but shall be again." the paintings are weird, it must be their future selves because they're a little aged in the paintings, even Dempsey says Nickolai gained a few pounds.
also whats with the writing on the walls in the different rooms.
"Brimstone to Damnation"
"Beware of the 6"
"knowledge itself is for the taking"
there is another behind the projector screen but i can't make it out.
