It starts off barely noticeable but, slowly, throughout the first movie and its sequels, it gets more and more obvious. This is actually an in-joke between Johhny Depp and the film's makeup department, who theorize that this scab is actually because Jack has syphilis.
The X scar on Jack Sparrow's face is as enigmatic as the Captain himself, and the idea actually came from Johnny Depp himself. He and the make-up team decided to add the scar to Sparrow's cheek, which, like many mentions of Jack's past, is designed to hint at an event - even if it's unknown what it actually is.
Thirteen years after Jack Sparrow made a deal with Davy Jones, to captain the Black Pearl for 13 years, Jones sent Bootstrap Bill Turner as an emissary to warn Sparrow that his debt had to be paid. Bootstrap Bill marked the pirate with the Black Spot, thereby making Jack marked for death.
Jack has two markings on his right forearm labeling him as a pirate; one, a tattoo of a swallow flying across a setting sun. [Traditionally a sailor gets this tattoo after traveling 5000 nautical miles at sea. Often a swallow is the 'first sign that land is near' and it means 'safe return home' for the sailor.]
Tia Dalma. Tia Dalma, or Calypso, is the sea goddess that sailors both loved and feared. It was implied that she and Jack Sparrow shared a romantic history due to her willingness to help out seafarers.
In Dead Man's Chest, Elizabeth kisses Jack Sparrow while they are fighting for their lives. Of course, it ends up she only did this to save the lives of the rest of the crew, but it was still cruel. She tricked both the men in her life with one action.
Angelica. Despite the character being a lead for all five Pirates of the Caribbean movies, Jack Sparrow only receives a conventional love interest in On Stranger Tides. The fourth movie introduces Angelica, the daughter of Blackbeard who Jack seduced years before the sequel's action begins.
Jack was shot by a Dalek and then brought back to life by Rose, Rose couldn't control what she was doing so she brought him back to life forever, Jack is now immortal. The Doctor wasn't comfortable with what had happened so he ran from the scene leaving Jack behind on Satellite 5.
TLDR; The reason Jack knows their language and why they made him their chief and see him as a god is because he has been there before, as mentioned in the first movie.
When Captain Jack Sparrow was given the Black Spot by Bootstrap Bill Turner, and told he was required to repay his debt to Davy Jones, Sparrow embarked upon a quest to locate the Dead Man's Chest, in order to save himself from a life of servitude to Jones.
Johnny Depp's research for his role in PotC led him to discovering that pirates wore kohl (along with grease and soot) to shield their eyes from the sun, and this is why we see Jack Sparrow wearing "eyeliner" in the PotC series.
When asked about some of the characters' health, screenwriter Terry Rossio said the likeliest cause of the yellow eyes is jaundice, a close cousin to scurvy; or, in the case of pirate captains Hector Barbossa and Chevalle, both considered ladies men, hepetitis.
A woman who tells lies that are truths and truths that are lies, Angelica was the daughter of the infamous pirate Blackbeard. Once a novice in a Spanish convent, Angelica was ready to take her vows until she discovered love through her affair with the notorious pirate Jack Sparrow.
Captain Jack Sparrow has a daughter. Birdie Sparrow has never met her father and her mother is dead, so she seeks to find her father. When she finally finds him, she can't te him the thruth instead works as part of the crew on his ship.
Example 2: Jack Sparrow in Pirates of The Caribbean- Dead Mans Chest. Fatal Flaw: He is afraid/ being a coward. Fatal Flaw causes one of s friends to turn against him and not trust him anymore. Tragedy/ End Result: Jack Sparrow is chained to the mast of a ship which is destroyed by the Kraken/ Jack Sparrow dies.
Jack wants freedom and to sail the seas for eternity doing whatever, whenever he wants. He loves adventure and is in some ways selfish, but he has a good heart. He's had many opportunities at immortality throughout the films and despite his flaws, he always makes the right decision.
Johnny Depp as Captain Jack Sparrow: The eccentric pirate captain of the Black Pearl. He is hunted by the Kraken because of his unpaid debt to Davy Jones. He is also searching for the Dead Man's Chest to free himself from Jones' servitude.
He is one of the most original, inventive, unexpected, unpredictable and delightful characters in movie history, and that is attributable to Johnny's determination not to take the roads most traveled. I think we all might in the end either see some of ourselves in Captain Jack, or wish that we could.
