Written by Ben Edlund.Directed by Philip Sgriccia.Airdate: April 19, 2007.Dean and Sam end up trapped in a hostage situation in a bank in Milwaukee, Wisconsin, with a former bank security guard who believes a half-man, half-robot is responsible for a string of robberies.Sam and Dean are investigating robberies of a jewelry store and a bank in Milwaukee, Wisconsin, which appear to be committed by long term trusted employees who then killed themselves right after the robberies. The brothers question Ronald Resnick, a security guard who was beaten unconscious by the teller who robbed the bank. They find out that Ron believes a "half-man, half-robot" which he terms "mandroid" is taking other people's forms, killing them, and committing the robberies. He points out glowing eyes on the bank security tapes, which he believes are laser eyes, as evidence that the robber was a "mandroid".The Winchester brothers realize that Ron has accidentally discovered a shapeshifter and that the City Bank of Milwaukee is located on the sewer between the two prior robberies. The brothers infiltrate the bank disguised as repairmen for the surveillance cameras just as Ron, on his own, enters the bank with a rifle and holds everyone hostage to try and flush the shapeshifter out, starting a police siege of the bank. After Dean is identified by the police and the FBI are called in, it's revealed that a detail led by Agent Victor Henriksen has been charged with apprehending Dean and have been chasing him since the incident with the shapeshifter the year previously. During the siege, Ron wanders into the sights of a police sniper and is killed. Just as the brothers manage to track down and kill the shapeshifter, SWAT storms the building. Sam and Dean escape by stealing SWAT uniforms and slipping away in the chaos.

Ron: Chinese have been working on 'em for years. And the Russians before that.
Conspiracy Theorist: Ron, who seemed obsessed by a connection between Cheeseheads and aliens before he decides to start hunting "mandroids".
Ron: I knew it, as soon as you two left. You aren't FBI. Who are you? Who are you working for, huh? The Men in Black? You working for the Mandroid?
Sam: We're not working for the Mandroid!
The Cuckoolander Was Right: Ron may be paranoid and unreasonable in his claims that a "mandroid" is responsible for the robberies, but he is onto something with seeing the pattern and spotting the flared eyes of the skinchanger's forms.
Agent Henricksen: It's become my job to know about you, Dean. I've been looking for you for weeks now. I know about the murder in St. Louis, I know about the Houdini act you pulled in Baltimore. I know about the desecrations and the thefts.
Properly Paranoid: Ronald turns on a flood light when Sam and Dean knock at his front door. He then asks to see their badges. Ron also made copies of all the security tapes from the bank because he thought the police would bury them.
Ron: The thing I let into the bank . . . wasn't Juan. I mean, it had his face, but it wasn't his face. Uh, every detail was perfect, but too perfect, like, you know, like if a dollmaker made it, like I was talking to a big Juan-doll.
Room Full of Crazy: The drawings, news-clippings, and pictures of aliens and Greenbay Packers on the walls of Ron's home. Among these is a wooden plaque that says, "God's peace be in our house", and a painting of a sailing ship.
When Sam and Dean present their fake FBI badges for Ronald to inspect, Sam's badge has the name Han Solo, and Dean's reads Jack Ryan. Harrison Ford has played both characters.
Ron has a hand drawn poster on his wall with pictures of people wearing cheesehead hats with yellow lines leading to a hovering mothership that says, "They are among us in Wisconsin (See Chart)" and "Cheeseheads are potent mandroid spies".
Agent Henricksen: Ex-marine, raised his kids on the road, cheap motels, backwood cabins, real paramilitary-survivalist type. I just can't get a handle on what type of wacko he was. White supremacist, Timothy McVeigh? Tomato, tomahto.
Dean: You got no right, talking about my dad like that. He was a hero.
