I honestly think..all we need to do is..Watch what he does with the key..🙂..and Only up until the part where he gets the heart and puts it close to his...and then what we see with the key/empty chest next is quite clear.."NO MAN was the right key to her heart except JACK" will looks at the empty chest..Norrie does...so does davy..
As he follows the key..he learns from his mistakes..he needs to learn from his mistakes to become the better man for Liz?..he took the key rather unfairly from norrie and will..so as soon as he gets it he falls into a grave..he then gets pulled out...(purgatory)
Movie 3:
he then loses it and it gets hooked on something..I think this is where he puts her on Sao Fengs ship he treats her as leverage here..he thinks he's all smart and that he's gonna see her again..as he runs in the wheel he's all smiling thinking he's gonna get it back but WHAM..he gets some sense knocked into him! This is where Liz is kidnapped from Sao Feng's ship and Jack realizes?..So its like "YOU IDIOT!" he gets up and THIS time he knows to avoid the bar (stop threatening her as leverage)..then there is a big fight over it in the middle of the wheel (I think)..jack is the Only one without a sword..(I think)..then will basically stabs it on the end of his sword.and Jack rescues it from him..he hangs up high (offered immortality?????),,but then falls down (No he wants to save Liz because he loves her)..then he has the key round his neck..and mr bad man gets knocked out..(Will forgets about Liz and Jack forever? thinking of Circe the witch/Tia (odyssey) offering to do this) The Only 2 people who don't drink Tia's "drink to ease the pain of remembering Jack" are Jack himself..and LIZ..in the Odyssey Circe the witch would hand out drinks in her house to people to make their forget their pasts..(all symbolic me thinks)..Odysseus and Eurylocus were the only 2 not to drink the drink..Odysseus was absent from the scene,,and Eurylocus did not drink..he ran back to Odysseus
there is a whole Odyssey resemblance as you can tell Odysseus turned down immortality so that he could save Penelope...don't even get me started on how similar she is to Liz.
I just hope I'm right 😂
