Kate:  So how 'd you get here ? How 'd you get onto this island ?
Patchy: I was recruited when I was _ twenty - four _ . I was approached by a man ...
Kate: I did n't ask you when , I asked you how .
Patchy: They brought me on a submarine .
Kate: So your people can just come and go whenever they want ?
Patchy: Go , yes . But two weeks ago our underwater beacon stopped emitting its locator signal . There was an event ; an electromagnetic pulse . It would be impossible to come back .
Kate: Why would you want to come back ?
Patchy: You would not understand .
Kate: Try me .
Patchy: I misspoke . What I meant to say is , you are not capable of understanding .
Kate: And why am I not capable ?
Patchy: Because you are not on the list .
Kate: What list ?
