all right i'm wrong sorry guys, no superhuman powers
btw, I think when Jill said "you think you can get away with this" to the guy sitting on the chair, Jill thought that guy was Chris, she said this because that guy was creating a storm while all three of them (the guy, Jill and Chris) were on the cruise, so that the guy could get free
but then Chris appeared, Chris said "I already have, Jill". Jill seemed to be surprised. then they were pointing their guns to each other for some reasons (idk)
then Jill said "did you... do you have it". I think Chris was infected by whatever virus (that made Jill tied Chris or whoever up, and maybe the virus gave uncontrollable superhuman power, and the superhuman power could create storms) and Jill asked Chris if he had already taken the antivirus or not.
Chris said, "maybe, you'll have to kill me to find out". It means the superhuman power gave immortality.
the guy on the chair said, "and what would you do if you find it, it doesn't matter, because you are already..." you are already infected?
i'm sorry if it doesn't make sense to you
