I never liked Jo because they couldn't seem to figure out what to do with her - make her a tough-ass hunter or a girlfriend for Dean. Unfortunately, IMO, they failed at both. Until BUABS where she was actually very good, and then they just made her disappear!

And yeah, Jared does tend to get the pretty girls, doesn't he? I totally agree that Sarah from Provenance was the absolute best. I wish they'd have her back on the show at least once more.
