Villa paintings

The Villa paintings are a series of paintings located in the map villa, some paintings are connected to the ARG.

One of the painting seems to have red markings around the lower half of the painting that cannot easily be seen.

• It's a number 4 and a 3-letter word with the second letter crossed out. Looks like 4 MAN?
  • this could refer to 4 dead men: Jeff Walter, Mikhail Rosenthal, Xeander Berg and Eric Kleinman This theory can be further reinforced just by looking at the characters forehead with an "X" on it and the wings on the characters back, which could imply death.
• It could mean FOR(4) NO(Cross) MAN(Word Man)
