Okay theory time.

Spoiler for Theory in here:

In the game we get a red text specifically saying that there are exactly 17 people on the island. Which means one person on the island cannot be there.

That person: Erika.

In the end game TIPs when you execute her it says that nobody is even sure if she was on the island during the murders. She could have washed up there, but nobody knows for certain because her body was never found. In short: Bern LITERALLY wrote Erika into the story. This is why she acts so odd and EP 5 is such an odd game - Erika shouldn't even exist on Rokkenjima at all. She was pretty much written into the story. This is why she wants a life so much off the gameboard - because her life itself is in limbo. Sometimes she exists and sometimes she doesn't.

There is also Featherine. Now Featherine is an author. She apparently (please note the apparently) wrote the bottled letters for EP 3-6. Every bottle after the EP 1-2 ones has no signature from Maria on it, because "Maria" didn't write them. Featherine wrote them. With EP 5 and 6 she decided to write in Erika, because the girl became such a controversy.

In short every game up to now is a cat box interpreted by other people, excluding EP 1-2. Because the cat box was destroyed (an explosion of some sort is confirmed to have happened) nobody knows the true story, so each game becomes an interpretation of the events that happened from the perspective of other people.

Sadly if this theory is true then we're in for a MAJOR mindfuck.
