Sam and Dean had broken the shell on the rock Dick Roman dug up (they stole the episode before) and found a tablet with writing on it. Soon after they got a call from Meg letting them know Cas wake awake, but... different. They go visit him and he's... cheerful. He seems to have found the funny side of life. When they ask him if he can read the tablet he hugs them, saying some about how it could only be the Winchesters who'd uncover the Word of God.
He also, notably, states "I love you guys!" when he hugs them.
