Look at it this way. Barbossa was captain of the Pearl, which already had a reputation for being the best ship in the whole Caribbean, for at least 8 years (from when little Will is attacked to when they nab Liz), and now that Jack is dead, he has the chance to kind of be a captain again, so he has to feel he has a knack for it and probably got attached to the Pearl the same way Jack did. So Jack is back, not giving up his captain's slot, so of course, jealousy and greed are going to play a big part in the whole thing AND in the trailer, Barbossa pulls a sword on him! There's going to be a lot of grudging there.
"guys, I'm telling you. it's Jack. however, it doesn't really matter, because we have no idea what the context of her scream is."---Kate
This is about what Liz is screaming near the end of the trailer when it's just her head above water. Most people are insisting she says Jack.
Well, Kate, she's definitely not screaming his name because he just did something great. She's screaming it to get his attention to save her from a watery grave or for him to watch out for Davy and James' Swift Sword of Power or something. And yes, she can scream for help if she needs it. She's not THAT b*tchy.
A photo won't tell you what she's saying. Keira's mouth is weird enough as it is since she pouts when she doesn't need to and she sets her jaw in weird ways. But enough bashing the most beautiful woman on earth (at least according to every single POTC character 😉 ). You have to watch the trailer and really pay attention to her doing it.
Think about when you scream. Where are your teeth? Where's your tongue? How do your lips move? Now think about when you say something that starts with J. The same questions apply. If they have the same answers, I'll gladly say she's screaming Jack. It's definitely not "Nooo!" It could even be the classic but effective "Aaauuuggghhh!"
