The l word "last word"?

ok i think that was a good episode, but the ending was terrable, i mean come on , give us some dam closure, also at the end when there all walkin to the police station, and they all start smiling why are they smiling u think they all were in on it, and y does jenny start walkin with them aswell, is that jus for the ending. also when the cop walks in and there all sittin on the couch they didnt look to disappointed that jenny was dead, i personally think she either killed herself and that tape was jus her sayin goodbye, (cause she did say to shane eariler in the episode, that she would leave everything to shane) or they all killed her, or one of them killed her and there all jus covering for that person, bette did look a little nuts when she confronted jenny by the balcony. and niki comin outta the bushes was a little suspicous tho. also i cant believe jenny took lez girls lol, what do u guys think of the episode, and who do u think killed her, also do u think they'll reveal it on "the farm"
