Commercial time. I mention this only because I get to see some long-haired Don Juan de Marco guy making sweet love to chickens in the El Pollo Loco commercials. In light of this episode, it seems like perhaps not the greatest example of advertiser/show synergy. Apparently this man promises his birds "a delectable dance of delight," and tangos with his dinner. I vow never to step into any place which regards amorous gourmands molesting their food as a positive development.

Anyway, back to the episode. In the lab, Sofia's eyeballing the bullets and coming to the conclusion that maybe the inscription "K DWM K 480C" could be significant. She begins running a comparison in a bullet database and finds a 9 MM entry that matches. "Deutschland uber alles," she says to herself. Because she's an Axis spy. I knew that walk was suspicious!

Sofia stiff-legs it into the lounge where Warrick's working and tells him, "I identified the casings found at the scene. They don't match Dax Blanchard's 9-mil. Did he have any other firearms?" None that were registered, it appears. Sofia hands over a photo of the bullet, noting that the stamp on the casing was a little unusual, as it's not every day you see bullets cranked out by the Deutsche Waffen und Munitions Fabrik. Warrick breathes, "That's World War II-era German." Sofia shrugs, "It's one thing to collect old guns -- old ammunition comes from a trophy. An enemy gun a soldier brings back from battle." And that's how Warrick is led around to the conclusion that the shooter's an old soldier.
