Another thing about the dialouge,Finn says there are others this time too. Finn has been having nightmares about the Snail. It wasn't until the last one that he got something about Billy signaling the premonition dream. And Finn had reason to surpress that dream, he didn't see the possed snail like we did in "in your footsteps" or "Mortail recoil" so how could he know how bad that snail was. Billy may still be alive, the Lich only possssesed him and he's fighting back.

Or he's dead. The simplest answer is usually the correct one.
