Season 8 - promises and threats *SPOILERS*

[Trust No One]

I particularly like how Kaley made this choice and the writers accepted it. Penny's new look is NOT a old bimbo look. Maybe Kaley (however subconsciously) wanted Penny to be taken more seriously.

I still think the Lenny needs to end for Penny to truly be taken seriously. Even a new job will do little if Penny is mainly seen as Leonard's girl.
