"just obsessed" wouldnt make her hallucinate 4 different people including a girl as him. The japanese has a term for people like Dave and Sierra. Its called yandere and the main similarities between all these characters is that they have obsessive love and they all went insane in some way because of this. Some even become psychopathic. Love is a powerful emotion and if not handle properly, it can make any person insane. Izzy is just exaggerated hyperactive or more or less psycho in some degree but Sierra really is psycho when it comes to Cody.

If you watch How I Met Your Mother, you might understand what i meant. If not i got a lot of shows to proof my theory but then again, it is mostly something you might understand if you watch Asian drama or a lot of police drama

And just because i hate a character doesnt mean i give him the highest level of insanity. Hell if not, i would have also give Beardo, Leonard, Staci, Max and Mildred (all whom i rank very low) insane as well but these are all just stupid habits that were just greatly exaggerated. And if you think im biased, read other blogs on how they view Zoke, Owen and Duncan (who are normally the lowest in character rankings) and see how these few people express their feelings. They are more tense than mind.

here is what i always think: NOBODY SHOULD LOSE THEIR MIND JUST BECAUSE OF LOVE.
