These aliens claim that they're unfamiliar with the concept that no two witnesses ever give the exact same account of an event. So how come they don't comment on the inconsistancies in testimony until they're questioning Stark? While both Aeryn and Zhaan give more or less the same story, there are some noticable differences.

Not only is Zhaan an unconvincing liar, she's also a shameless kiss-up.

It was also kind of cute that, during Crichton's recounting of the events, everybody was mispronouncing it "Plakavoids".
