Actually, I would say pretty much all the BDHs have gone creepy:

1) Nathan had Caleb the Dark Preacher in Buffy S7;

2) Gina had Jasmine in Angel S4;

3) Alan had Child Molestor Man on CSI or Sonny in I, Robot;

4) Adam was Marcus Hamilton on Angel S5 and probably has more than one other creepy guy on the CV;

5) Morena has her Ori-human hybrid (haven't seen SG-1 S10 yet to get name confirmation)

6) Jewel has been a Wraith (space vamp) on Stargate Atlantis and her role as Daisy on Higher Ground was definitely a shock to see her being anti-Kaylee

7) Sean was a pervy "Girls Gone Wild" style video producer and possible necrophiliac on CSI

Summer and Ron seem to have gotten away with not having truly creepy roles on their CVs 'less you count Summer's turn on The 4400 as Tess...but that role is a bit too much like River to get classified as creepy in my mind. And I am sure Ron's been a baddie at least once in his career...just haven't seen it yet;)

Ok don't do that. I still have to watch it...

Nope. Never a fan of either series. Just didn't find them appealling

Heh, so I take it you didn't see Nathan on Buffy.

Or Gina on Angel (which was primarily creepy 'cause she was being so nice).
