Y'know what, I always just assumed that Jimmy was trying to whack Karen. If not, why didn't he walk her over? Those guys "loading boxes" were not something to be irrationally paranoid about -- guys in a dark room? -- I could swear I heard one of them say "there she is"... I don't know for sure... but I always got the impression that she was to be whacked for some reason. Next time I watch it, I'll pay more attention to see if I can tell better.

As for the airline ticket, I think Turnbull's right... just a trademark thing...
