Jack’s still cunning in 2 & 3, in 2 he manages to bargain again (temporarily) with Davy Jones over his soul which gives him more time to look for the chest, manages to get Will onboard the Dutchman to steal the key, almost manages to get Jones’ heart, persuades Elizabeth to help him instead of looking solely for Will, convinces Norrington during their fight that Will is actually to blame for his predicament, and even manages to abandon the Pearl before it’s attacked again with only Elizabeth noticing.
