"Cas, you shouldn't have to go back," Dean pleaded. "Stay here where you'll be safe."

"No. I have to make things right. I'm sorry, Dean," he said.

Tears formed in Dean's eyes. "What if she kills you?" He said.

Cas grabbed his hand.

"I won't let that happen. See you in school."

He turned to leave, but Dean refused to let go of his hand.

"Dean, let go. I need to go back."

He let go.

"Ich liebe dich," Cas said as he walked up the steps of the bunker and out the door.

Dean went to his computer to see what his friend had said to him.
