Back to the present. It's not clear how much of this Dean has actually said aloud to Sam, because all we get is a close-up of Dean's face and his thoughtful expression. For all we know, Sam has been staring at a silent Dean for the past three minutes.
They finally finish their 1800-mile trip and arrive in Michigan. Their first stop is Channing Ngo's dorm room to see if her ex-boyfriend Kevin has been to visit her. She's disgusted at the very thought. Not only did he disappear for some silly "mission from God" thing, but he's not even going to Princeton. She wants nothing to do with her ex. This leaves Sam and Dean to try to figure out why Kevin would have come to the campus if not to visit Channing. Good Lord. Sam's hair is so long it's actually billowing. It's like drapery billowing in the breeze.
Meanwhile, Channing turns out to be a demon. She stabs her roomie in the throat and catches the blood in one of those ritualistic cups like Meg had. She chants something. The blood bubbles. "The prophet has not yet shown his face to me," she says over the cup. "But you should know Dean Winchester is back." Demons really need to invest in cell phones.
Sam sits outside somewhere, typing away on his laptop, when he sees a woman walking a dog. This inspires him to have a flashback to the night he met Amelia. He bursts into the veterinary clinic, carrying a dog and a bloody towel in his arms. An assistant rushes him back to the exam room, but she doesn't seem very hopeful about the dog. Sam's about to go all Shirley MacLaine in Terms of Endearment on her when the vet comes in. She gives Sam a look like he just farted at a society dinner and asks the assistant to show him out.
He snaps back to the present when Dean sits down across from him. Looks like Dean got quite the workout in Purgatory, because he is about to Hulk his way out of that suit. If you listen very closely, you can hear the shoulder seams straining. But back to the matter at hand. During the rest of this scene, Dean munches on a burger and makes happy little moaning sounds, so maybe he's starting to feel like his old self again. He reports that he hasn't found anything on Kevin. Sam has had more luck and expo-babbles about how he found Kevin's wireless router. God's littlest prophet is holed up in Fairfield, Iowa.
