One week later.

Dean, Sam and Meg were standing around a grave. Cas’ grave. After hours of interrogation the three of them had been released, but Cas’ corpse had been confiscated until now. There had been an autopsy and of course the police wanted to know where he’d get the burns. Sam, Dean and Meg had agreed on a story about self-defense and once the police had bought it they were free to go.
They heard loud voices and laughter. Sam turned around irritated and saw a gang of young people heading towards them. They had two bottles of booze with them. They stopped at the grave. One of them raised his bottle and spoke loudly: “Here’s to Castiel Novak. May his raping, murderous ass rot in Hell forever”
The next moment he lay on the ground. Both Sam and Dean had jumped on him and were working his face with their fists.
One of his friends picked up the bottle and smashed it against Cas’ grave. He grabbed Meg and held the broken bottle against her throat.
“Hey!”
Sam turned around and saw the danger Meg was in. “Dean, stop”
But Dean didn’t want to stop.
“Let go of him or your friend is dead” Meg’s attacker threatened.
“Meg isn’t my friend” Dean muttered. “My friend already is dead” But he stopped beating up the guy anyway. He stood and conjured his weapon. He aimed it at Meg’s attacker. “Let go of her”
The guy pushed Meg on the ground and joined his friends again. “Now, if I ever see any of you scumbags here again, I’m going to pull the trigger”
The gang quickly walked away.
“You shouldn’t have done that” Meg mumbled.
“What? Saving you?” Dean snapped. “Don’t flatter yourself. I didn’t do it for you. I did it for Cas”
