Meanwhile, Mia and Warrick are doing laps through the Labitrail. Sadly, that's not a euphemism for anything. These two are remarkably chemistry-free this week. Mia's explaining to Warrick that the milk in the bottles is not formula, but human breast milk. "ALL of it??" Warrick asks, now dreading the prospect of going back to find the secret stable of wet nurses required to pump out 48 bottles of fresh breast milk on a regular basis. He confirms it wasn't Donna's, and Mia dryly notes, "No, the Widow Eiger's DNA was definitely not a match." Reluctant as I am to ever take shout-outs, I might consider this as one; "the widow whomever" is one of my favorite addresses for bereaved women in these recaps. Mia also passes on the news that the one inexhaustible donor who pumped all those bottles was also the one wearing the dress Nicky and Catherine commented upon. "So we're looking for one very tired milkmaid," Warrick accurately observes.

Speaking of people on motherquests, deliberate or otherwise, Nicky's looking at a toy chest he brought back from the nursery to the lab and explaining to Sara that it looked like the one in the store, except the one in the store was twice as deep. "Well, he did like his secret spaces," Sara says of the dead, and the two of them peel off the front of the box to discover that indeed, it had a false bottom, and contained within the secret compartment are dozens of files. Among the subjects of the files: Sy Magli, Sam Braun, and Rory Atwater. I believe we're all familiar with the last one as Sheriff Xander Berkeley. I wonder what's in his file -- he sold drugs to Sid Vicious and Nancy Spungeon? Nicky says the rest of the files include "gaming commissioners, judges, pro athletes..." and one unlabeled photo of a baby standing in a crib, drinking a bottle. The date on the photo's 12-20-01.

But why worry about a mystery baby when you can page through Sy's file instead? Evidently, he was a man who had varied tastes; in one shot, he's seen looking at a teenaged girl and wooing her with his patented "Uh, right..."
