Summary: Keeping Jack both busy and in the bunker seems like a great idea to Sam, Dean, and Cas, giving him free rein to catalog all their previously uncataloged books. But when Dean walks in on Jack reading from a book with Cas in close proximity, that free rein might prove problematic. Though where’s the harm in things unspoken becoming things that are said out loud?
