yeah, the fifth season (as you will see) feels entirely like a build up to the sixth. and yeah, i still like some of the characters; namely eric, russell, pam, lafayette (when he's written as lafayette) and that's why i watch still too. trashy tv. still fun sometimes.
and in answer to the last one, i don't know. haha. i can't really remember the fourth season too well. i know they both fed on sookie, but beyond that, i forget. sorry.
