Deb ?

Did anybody else think of the fact that maybe deb knew were it was the grave and that is Wes and deb went to go see Wes but pretended to be a phantom invade another phantom was there ? And the person they saw is actually deb and not Nelson or maybe it was Nelson or somebody else who killed wes and he was making sure there was nobody there because he planted hearing devices in the studio and heard that they were going there ?
