In her first episode, it was said that Iris's hostage takers were two Germans. Here they are three Dutchmen.
Iris says her hostage crisis took place three years ago, so it
would be in 2003. However, in 2003, when Iris came on to the show, it was referred to as 'last year', ergo 2002. One could try to blame the episode's delay to the mistake, but since it was scheduled for a 2004 airing this means the crisis took place in 2001- one year too far.
