Was this a repeat or a new episode? Just curious...

This episode began with lady being found in a sandbox at a playground... afterwards a warning of "brief nudity and adult situtions" adorned this opening.

A-story: Katherine and Gil uncover the (nude) body and begin to process it on site. While in the lab analysing the body, my wife and I counted three nipple shots, one of them prolonged. (I bet necropheliacs got a kick out that.) They finally trace her back to a dominatrix establichment. I loved the scenes of Gil and "Lady Heather." I found it very funny that "Lady Heather" was able to deconstrcut Grissom at a glance and the way she immediately profiled the photo of the lawyer lady and her husband. "Lady Heather, you are a great anthropologist."

B-story: Warrick and Sara work an armed robbery case at a check-cashing store. While the story was small, it kept the others busy.

Line of the night:

"Katherine, you wouldn't want to take Greg Sanders (DNA freak) and cover him in liquid latex and shove straws up his nose... he'd enjoy it too much." - Grissom

Repeat from last season.

You're right, I check and episode guide, it was episode 31: Slaves of Las Vegas.

Thanks.
