Spoilers - Huge plothole, completely ruins any sense of realism within the movie- You've been warned!
Didn't Claire Wyden already have three vials of the antidote in her bag before Kate slipped in that extra one prior to George getting on his Chewit advert face on with her?
He'd be poisoned and couldn't do what he later does in the movie!!
Completely pulled me out of a very believable situation that did. Ruined an otherwise highbrow cinematic masterpiece.
WHY???!?!
