Sun gets intelligence on Ben and Jack, a gun

After Kate leaves Aaron with Sun at the Century Grand Hotel, Sun receives a delivery from Derek. Sun takes the package to her room and pulls out some surveillance information. Upon inspection of the text, various online sources have confirmed the text was lifted from an online game. Check out the text of the documents here. She then pulls out photos of Ben and Jack at Hoffs/Drawler Funeral Parlor, presumably taken when they were taking Locke's body. Next, Sun pulls a box of chocolates out and pulls a gun from under the candy. It seems conflict will soon arise.

So who was doing the surveillance for Sun? Does the gun mean that she made a deal with Charles Widmore to kill Ben? What's with the strange text of the surveillance being taken from a game? The producers know that fans will freeze and read the text, so why does it seem to have no relation to Lost?
