Later, Sam and Dean regroup at a cafe. Dean didn't find anything spooky in his clandestine pokings around Paul's house, which for some reason he's only telling Sam now instead of on the ride over. Dean consults his laptop and discovers a similar murder two days after the jogger's. This one took place in Ames, Iowa. Sam thinks for a second. "Well, Paul was here being questioned. There's no way that could have been him." Why he thinks it would be impossible when it's only a three-hour drive away is a mystery, but in this case he turns out to be right. A police officer named Arthur Swenson was arrested for the murder. "This is exactly what happened six months ago," Dean says. "Minneapolis, then Ames." Sam's considerable brow raises in surprise. "Guess you missed that one," Dean says. Sam looks a bit stung, but remains silent.
They head for the County jail in Ames and talk to someone in the sheriff's office about the case. Swenson was a great cop by all accounts, until they found him covered in blood and crying not far from a pizza delivery guy's heartless body. Swenson had been in court testifying all week, which makes Sam rule him out as their Minneapolis murderer. We the viewers know this to be the case, but again, it's just a three-hour drive. Or hey, here's an idea! Maybe the perpetrator is using some supernatural method of transportation. If they're going to make us sit through a boring procedural, they should at least be thorough about it.
They go to question Arthur Swenson, but the guy's not a really great conversationalist. He rocks back and forth, clenches his fingers together and chants nonstop under his breath. Closed captioning insists he's saying "K'uhul ajaw, Cacao, shi-jiiy," but it sounds like he's imitating a washing machine on the "pots and pans" cycle. Sam records whatever Arthur is chanting but doesn't recognize it. Dean notices that Arthur has one blue eye and one brown. "Hey Arthur, did you do this alone?" Dean asks. Arthur just keeps rocking back and forth and repeating his dishwasher chant. Sam gives it a go: "Did some invisible voice tell you you had to kill?" Arthur bangs his fists into the table, chants a little louder for a moment, but otherwise seems unaware they're even asking him questions. Dean sprinkles holy water on Arthur's arm. Nothing happens. Whatever has gotten into Arthur isn't a demon. "Arthur, you wanna tell us why you did this?" Dean asks. All he gets back is more chanting.
Later that night, alone in his cell, Arthur is still chanting. You'd think he'd be in a psych ward somewhere for evaluation. His voice is hoarse; the words come a little slower. He's been at this for a long time. As he rocks back and forth, he grips a metal brace from his bed frame and rips it free. He grabs the metal with both hands and raises it to his eye. The camera moves to the hallway outside his cell. A moment later, there comes a sound like a salad tomato being crushed underfoot. Arthur screams. The chanting stops.
