basically its barbossa telling Sao that Jack holds 1 of the 9 pieces of 8 and sao see's a melting tattoo on one of the guys and thinks that Barbossa and Liz are betraying him and grabs the guy with the tatoo and treatens to kill him....Barbossa says "He's Not ours" and Sao says "He's not urs and he's not mine...then who is he with" then everyone pulls their weapons out and then Bellow Gibbs says Weapons and the pirates slide swords up through the creeks to Liz and Barbossa and then the fight begins!
