Perfect vengeance. I really did get a sense of claustrophobia reading this. First in terms of the confines of the ship, but I think highlighted by the 'fat man' who takes up all the space, in more ways than one. The whole thing was just so vividly drawn - bravo!
Thank you @lazarus-wist for such a lovely comment on this story. I'm glad the imagery of what I had in my noggin came through :)
