Cut to Brass and Gil visiting Lepidro clinic. By this, the 100th episode, even the most casual viewer will have picked up the etymological and entomological clues necessary to know it's a play on butterflies, a.k.a. the order Lepidoptera (from the Latin "lepid-" [scale] + Greek "pteron" [wing]). But the play here is not on scaly people who fly a lot, but on the people who are breaking out of a larval cocoon into a beautiful butterfly state. Y'all, I have had it with the Lepidoptera metaphors lately.

As Gil and Brass come inside, a youngish woman -- pretty in a blandish, Kimberly Williams kind of way -- bids a little girl adieu with, "Bye-bye, scrumptious pumpkin." The kid tells Amber to beat it, and the man with her smiles genially at the law enforcement types. Oh, he'll stop smiling soon enough. His name is Francis; Dr. Lavalle is his wife. The little girl comments, "Grown-ups always do that," and without missing a beat, Francis replies, "That's gender stereotyping, honey." Ha! This totally reminds me of living near Berkeley. Brass and Gil introduce themselves and break the news of Wendy's death in their own inimitable fashion. Francis leads them outside to what really does look like north Berkeley, what with the Craftsman-type use of natural stone in the architecture, the seamless incorporation of outdoor and indoor elements in the yard, and the lush, green grass. After a snippet of conversation establishing that yes, transsexuals are just like us in that they go to church, Dr. Lavalle gets yanked out of group and into another scene.

This next scene has her cataloging how she travels the world because "6000 women a day suffer genital mutilation." Gil asks, "So you travel around the world, treating victims of sexual treachery?" Dr. Lavalle points out, "You don't have to travel to find the genitally disenfranchised." Brass asks if Wendy was among those, and Dr. Lavalle tells us Wendy had been denied surgery, and she had been working "on what had made [Wendy] an unacceptable candidate." Hint: Wendy was impatient. She was also "passing" -- something Dr. Lavalle didn't recommend, but Wendy was adamant that her fiancé Aaron wouldn't know the truth. And she pins this as the reason Wendy was so agitated when she came in for an individual consult the night before. During all of this, Dr. Lavalle has neatly managed to distract the CSIs from finding out how exactly Wendy found the doctor who performed her surgery. I'm still trying to figure out when she had it. Wendy's whole gender timeline is really murky. Gil asks if Dr. Lavalle videotapes sessions, and that idea gets shot down as a violation of patient privacy.
