Ion is in the middle of an existential crisis when Castiel finally works up the strength to knock him upside the head. While Ion is lying prone and helpless, Castiel jabs him in the eye with the slug he just fished out of his gut. For some reason, this kills Ion more or less instantly. Are the eyes of an angel especially vulnerable?
Back to more sitting and talking with Metatron and the Winchesters. Dean sums up for us what has already pretty much been established: "So, you've been holed up here, or in a wigwam, or before that in a cave... listening to stories and reading books?" Metatron laughs like a naughty Frenchman. "What you brought to His earth... All the mayhem, the murder. Just the raw invention of God's naked apes - it was mind-blowing!" He seems to mean all this as a compliment. What really impressed him, though, was mankind's storytelling. "That is the true flower of free will - at least as you've mastered it so far," he says. He goes on gushing about all the books he's read, and he still hasn't read them all. Obviously he hasn't gotten around to Chuck's books, yet, or he would have known who the Winchesters are. Sam has had just about enough of all this and begs Metatron to kill him. "All this time you've been hiding here, how much suffering have you read over?" he asks, pulling the gun to his chest. Dean gently nudges him out of harm's way and faces Metatron himself. He takes the scribe to task for not looking after Kevin Tran, which, you know, is true enough. But it's not like the Winchesters have much room to talk after failing to invite Kevin to their totally evil-proof bunker.
Houseboat. Kevin indulges in a little taunting as he flaunts that Sam is now up to the third trial. "You have no idea what's on the tablet," Kevin says, holding up the half that's been in Crowley's possession. "The power you could have gotten from this, if you hadn't been running around like a chicken with its head cut off..." Crowley finally gets pissed off enough to grab Kevin by the throat and shove him up against the nearest wall. A moment later, angelic light pours out of Kevin's eyes, then explodes, sending Crowley flying through the as if shot from a circus cannon.
Kevin has been brought to Metatron's hotel room. He seems fairly dead until Metatron places a healing hand over his chest. Kevin's heart beats again and the bruises around his throat fade. Even the circles under his eyes lessen. He remains dutifully asleep so that Metatron and Dean can have a talk in the next room. "How did you get past Crowley's angel warding?" Dean asks. "I'm the Scribe of God," Metatron says, like duh. Dean is intent on shutting the Gates of Hell, and wonders if Metatron is going to help. Metatron says it's Dean's (and Sam's, I guess) choice to close the Gates. "But you're going to have to weigh that choice. Ask yourself: What is it going to take to do this, and what will the world be like after it's done?" Finally! Finally somebody (besides recappers and viewers) asks what the Winchesters should have been asking themselves since they first learned of the trials. Dean thinks about this for a while, but Kevin wakes up before any further discussion can take place. He has Crowley's half of the Demon Tablet. "Third trial," he says. "What is it?" Sam asks. "To cure a demon," Metatron answers for him. Sam's face goes, "Ruh-roh!" It's like a dog out of a Scooby Doo cartoon!
