Sam is finally starting to figure out why Dean and Cas are so intense around each other. It makes sense, really. Granted, nothing is going to come of the longing glances and secret pining unless somebody does something. Sam takes it upon himself to do that something. Buy as it turns out, getting Dean and Cas together is more difficult than he imagines. When the case they're working-- a creature straight out of the Lord of the Rings-- reminds him of a good friend, Sam decides to call in the big guns. Charlie shows up to help with operation Destiel.
