(Something I didn't mention in the Intro was that this theory couldn't happen if it wasn't for Matpat)
Maybe in The Caribbean somewhere in the line,Jack Sparrow was on the black pearl. "Mr Gibs" came running to the wiel of the pearl.
"Where we be headed Cap'n?"
"Aye,Let me check me Compass"
Jack looked at his compass but it was just spiralling.
'Ey?But I know what I be want'n...Is it broken?No it can't be,I would have done somethin' idiotic' Jack said to himself.
Jack looked forward. Infront of the pearl there stood a shadowed figure. The shadowed figure came closer.
"Cap'n?Cap'n...JACK!" Gibs yelled furiously
"Aye! sorry thought I saw somethin'. Mr.Gibs I think there be somethin' wrong with me compass"
"No cap'n there's nothin' wrong it. . ."
"What do ye mean?"
"Cap'n,its pointing North"
Jack blinked a few times before he could have seen it wasn't broken but it was pointing North
"Aye,Mr.Gibs we be headed North,to Tortuga exactly"
"Aye!"
Gibs chased the crew to their stations and they went sailing to Tortuga.
"Mr.Gibs!Come and take the wiel,I have to track on the map."
"Aye!"
He went downstairs to the map table and sat on his chair. He began to track their steps, suddenly he heard a voice in the shadows of the pearl.
"Ye be lookin' for somethin',or should I say someone"
Jack had shivers down his spine
"What ya be want'n?Well ya ain't getting somethin' from me!"
"I want to relieve you from your pain, relieve you from your horror. I be want'n to relieve your suffering aswell"
"Pain,horror, suffering?*laughter*I have no such things"
"Your friend's death doesn't say otherwise."
Jack had a flash back of how Barbarossa died, falling into the abis. But there's somethin' Jack was always hiding. Ya know his hallucinations?
They got worse overtime after the death of Barbarossa.
"I think it's best ye be headed to Tortuga ya know. Ye friends Will and Elizabeth are waitin' for ye there"
'how come they be waitin' for me there?Is it somethin' important?'Jack asked him self
"How do I know ye not be liein'?"
"Consider it as me showing how I look like,savvy?"
Jack couldn't understand, He used "savvy" alot aswell.
The voice came out of the shadows. It was the shadowed figure he saw.
"Your not real your an hallucination"
"Your right ya know, but what exactly do I look like?"
Jack couldn't believe his eyes. The shadowed figure looked exactly like Jack,but only in shadow.
His face was black like a shadow could be,as for his whole body aswell. Around him was strange shadowed particles.
"I promise ye, they're be waitin' for ye there."
The shadowed like Jack vanished from fin air. Jack had no choice but to go to Tortuga.
When he got there,the shadowed figure was right. Will and Elizabeth were there.
"Here we be meatin' again Will Turner."
"Jack?" Elizabeth replied
"Aye."
