Dean couldn't wait until he could see Cas again. He hoped he would still want to be his friend. He asked Sam to drop him off outside of the school. 

"Okay, just don't get into any fights."

"Bye, uncle Crowley!" Dean yelled as he was going out the door.

""Bye, Dean," Crowley called from the other room. "Thunderstruck will be here when you get back." He said, referring to Dean's pet hellhound which he still thought was a regular dog. Sam still had no idea how Crowley made it visible.

"Stop calling him uncle Crowley. Please. I beg of you. Please stop," Sam pleaded.

Dean grinned. "No."

When they arrived at the school, Dean quickly scanned the area for his friend. He got out of the car. He found Castiel sitting under a tree, reading a book.

"Hey, Cas!" He exclaimed. "What are you reading?"

"Les Miserables," he replied, putting the large book aside.

"Can I see it?"

Cas handed him the giant book. Dean opened it to discover that he couldn't read a word of it.

"What language is this?"

"French."

"You speak French?"

"Fluently. Along with German, Russian, Spanish, Latin, and one I made up called Enochian."

"Okay, show off. Count to ten in German," Dean joked.

"Einz, swei, drei, vier, fünf, sechs, sieben, acht, neun, sehn."

"Wow. You really can speak German. I can speak a little bit of Latin. What's your favorite language?"

"Either German or Enochian."

"Cool. What's 'I'm hungry' in German?"

"Ich habe Hunger."

"Let's go get something to eat. I know a diner that has great pie. Want to come?"

Cas got up and walked with Dean. They spent most of the trip debating over which AC/DC song was better: 'Back in Black' or 'Thunderstruck'.

At long last, they reached Judy's diner.
