Speaking of people who have a fractious relationship with the outside world, it's Sara and Mia. Sara had Mia test the blood on the pads she collected, and while Mia can confirm it's Wendy's blood, it's a) not menstrual, and b) containing an anticoagulant, so Wendy was having blood drawn and putting it on pads. "She was faking her period," Mia said. The lab tech -- who is still having problems reconciling the chromosomal read on the situation with the social one -- wonders why anyone would do that, and Sara muses, "Well, she was living as a woman and that's part of it? I-I don't know." At least Sara's trying to regard the evidence from the victim's perspective. Mia says, "You don't draw your own blood. She had to have had help." Sara thinks that her blood-drawing assistant may have been the same doctor who was prescribing all Wendy's meds.

Speaking of people who could maybe benefit from a little medication, in bounces Liam, reporting to Gil that he's run down all the pills in Wendy Garner's bathroom, and "for the record, I really like having a penis." Gil has the look of a man who acutely wishes he were deaf again. Liam backs away from the oversharing ledge and explains that Wendy was taking estrogen conjugates obtained from Mexico, then strikes a blow for health-care reform with, "HMOs don't consider being differently-sexed a life-threatening condition --" "So patients resort to Mexican pharmacies," Gil said. Wendy was also taking premarin, some massive tranquilizers, painkillers, and a broad-spectrum antibiotic. Liam yanks his mind away from his plans for an Up With Penises party to opine, "Sounds like a post-surgery cocktail to me." Gil's phone rings right then and he has this conversation: "Grissom...yes...Mimosa? …Yes…today...the Apple Martini, one o'clock. I'll be there." Liam stands there, disbelieving that people are calling Gil up to beg for lunch dates.
