Hey, guys I just thought I would make a thread for a theory of mine about the game. I've posted this theory in other threads, but I just want to see what everyone thinks of it. Feel free to say what you want, don't go easy on it. Thanks. Gotta go to work, later.
I 'm going to go off the Voodoo lady's trance about Morgan. Based off that I think Morgan will be severely injured and tell Guybrush to go on before dying. This holds water as the voodoo lady screams when in the trance before leaving it. The trance also makes mention of a skull, so I think Murray will appear in chapter 3 and join the crew along with Winslow, Morgan, and Decava.
LeChuck is revealed to be behind everything. He planned to be turned into a human and spread his evil so that he can control others and use the pox to make Elaine fall in love with him. The flower he gave her was infected with the pox and Elaine breathed it in, allowing it to affect her mental state, but not her body. LeChuck controlled all the poxed pirates and monkeys to do his dirty work in order to appear good to Elaine.
He manipulated the pirates to attack spinner cay to collect the artifacts. When Guybrush arrived, he altered his plans and had him get them to summon the sponge. His plans were for the sponge to reveal itself so that he could use to gather other voodoo powers, not from the poxed pirates, but from all other voodoo wielding people such as the voodoo lady. He would use it to become a pirate god, but still have an army of poxed pirates under his command, Elaine fully under his control and at his side, and all the seven seas. While Guybrush summons the sponge, LeChuck further tightens his hold on Elaine and makes deals with De singe to kill Guyrbush once he gets what he wants from him.
Once the sponge is summoned and brought above the ocean, LeChuck and the poxed pirates subdue it while LeChuck arrives on Guybrush's ship with Elaine, now under his complete control, and De Singe. Morgan allows them to capture Guybrush for her gold, but feels horrible. LeChuck explains his whole plan, but then mentions that Guybrush can not be killed because the pox is in his essence. To counter that, LeChuck plans to have De singe extract Guybrush's essence to make his elixir and insure Guybrush will die when the time is right. Morgan goes with De Singe to Flotsam with Guyrbush and Murray, who is in his pocket, as prisoner. LeChuck locks up Winslow and Decava in the brig of his ship and uses the sponge to extract enough power to become a pirate god. He takes the sponge and his entire fleet of ships to the Rock of Gelato, as it's the prefect place to extract all the power from the Caribbean and that site and conquer all the seas.
On Flotsam, De Singe reattaches Guybrush's hand, extracts Guybrush's essence, ridding him of the pox, prefects his elixir, and gives Guybrush over to the court house where a trial and execution is set up. Morgan interferes and sacrifices her life to save Guybrush. Guybrush tries to save her but Murray will tell him to go on with his journey. Morgan will say that the skull is right and that there is no escaping his fate before dying. Guybrush is infuriated and attacks De Singe who gets gravely injured by one of his weird scientific experiments in his lab. In a last ditch effort before dying, the doctor drinks his own elixir and becomes an undead monster.
Guybrush flees and, with the help of the voodoo lady, who goes with him to find Decava, catches up to LeChuck back at the rock of gelato. He frees Winslow and Decava from LeChuck's brig and they help him free the sponge. The sponge gives the power to counteract LeChucks' by making Guybrush another god. De Singe appears and joins in the battle, aiding LeChuck's pirates. After Guybrush defeats LeChuck, the sponge takes away both their god forms and sucks up all of the pox from everyone, including De Singe. This makes all the poxed pirates return to regular, non evil, grog swinging pirates.
De Singe dies as a result, the pox is put back into LeChuck who is infuriated, and Elaine is returned back to normal. The voodoo lady gives Guybrush the sword from chapter one and Guybrush and LeChuck go into an epic sword fight. Through a very clever series of events, Guybrush stabs the sword into LeChuck and destroys him. LeChuck's corpse is destroyed and his voodoo essence is sucked into the sword, trapped in an eternal limbo. Decava and the voodoo lady start anew and Guybrush and Elaine sail off to the open sea with their new crew of Winslow and Murray. The last scene is Guybrush giving Elaine back her wedding ring.
