After finally convincing Cas to leave his stolen car behind and get in the Impala, they all headed back to the bunker.

"I don't know why you didn't let me drive!" Cas exclaimed.

"You're a menace to society, that's why!" Dean said, looking in the rear view mirror. "You almost got into, what, three accidents in the time we saw you! Who knows how many other people you endangered before you caught our attention!"

Cas looked away guiltily, knowing that Dean was right, but not willing to admit.

Sam raised his eyebrows at his brother, as if to say "Was that really necessary?" Dean just shrugged and looked back at the road. They were silent the rest of the way there.

Once they had settled in at the bunker, Sam grabbed some books for research, and Dean stared at him.

"What?" Sam asked, eyeing the gun in his brothers hands.

"What are you researching for?! We know to kill demons! Grab your stuff so we can gank 'em!"

Sam shook his head. "Dean, you realize that there are AT LEAST three demons? Even when Cas had his grace, that would've been risky! We don't even know how many there are yet, let alone what they want! We need to prepare, not just run in there and hope for the best!"

"He's right, Dean." Cas said quietly, looking sad. "If I hadn't been a fool and trusted Metatron, I could've taken care of the problem myself."

Sam and Dean looked at each other, then Sam turned and left the room, knowing Dean needed time with Cas to sort this out. Dean had barely taken a step forward before Sam came back in and grabbed some books. "Might as well get started." he mumbled awkwardly, before practically running back out of the rooms.

Cas looked at the floor, not lifting his chin until Dean was standing in front of him. "I'm sorry-" Dean cut him off by pulling him into a tight hug. Cas slowly wrapped his arms around Dean, burying his face into his neck. They stood like that for awhile, until Cas started to feel better. Dean never had to say anything to make Cas feel better.

"Let's go hep Sam with that research." Dean said, grabbing Cas' upper arms and smiling.

Cas smiled too, after awhile. Maybe this could work out after all.
