I was looking through my DS tapes and noticed that in all the episodes and I noticed the large amounts of "I don't understand"s said in the episodes and not just by Vicki. In like the first 4 weeks of the series, the only person I remember saying 'I don't understand' was Elizabeth but then later on all these people start saying it...Vicki, Maggie, even Julia. With the exception of Julia, it seems to me that Vicki Maggie and Liz are all part of the clueless crew at some point
