So, I was rereading the episode review for "Through A Lens Darkly" and the scene toward the end where Daria locks herself in the bathroom stall after revealing to Jane that she's not wearing her glasses or contacts for reasons of "sheer vanity". Both Jane and Jodie couldn't get Daria to come out, but Brittany comes in and says the right thing to help.

So it makes me wonder... is Brittany the stereotypical blonde, not very intelligent... or is there something more there?

My opinion is that Brittany has the capability to be more, but has fallen into the trap. I evidence this based on the instances where she steps out and shows some intelligence, like "The Daria Hunter" where she comes up with a plan of attack during the paintball game.

What say ye?
