Dean downed the last of his beer and checked on his dinner. As much as he loved to cook, sometimes he wanted something quick and easy. And he didn't have Sam around to comment on his unhealthy meal choice. (His brother was taking their few days off to collect some books they might need.) So, he was taking it easy for the next few days. Catching up on some movies, doing a bit of research. Sleeping in his own bed. And eating a nice quiet meal.
He had his dinner on the table when he heard a crash from one of the bedrooms. Leaving his food, Dean raced towards the noise, grabbing a gun and knife that just happened to be lying around.
He got ready to rush the door to the room when it crashed open. Levelling his gun at them, he tried to see who they were. They'd made sure that the bunker had good defences which only allowed a few non-humans in.
The angel currently fighting the demon? Being one of them.
"Cas."
Dean shoved the gun in his waistband and ran into the fray, wielding the knife. He managed to get a few good aims in before the demon? Dean still wasn't sure. But it was Castiel who finished the thing off. Driving his angel blade into the thing. It screamed. Light. Gone. Dean clapped the angel on the back.
Which turned out to be a mistake.
The angel turned on him and Dean was once again fighting for his life.
Just this time it was against his best friend.
"CAS!"
The angel was just about to stab him, when he blinked. Stumbled backwards and slid down the wall. He seemed lost for words. Which taking in his appearance Dean was surprised the angel had even been able to stand.
He knelt down and took the angel blade. Dean turned his head and took a look behind him at the bedroom. It was the one Cas used whenever he was at the Bunker.
"You owe me a door."
"Sorry about that. I was aiming for somewhere safe. I thought I'd lost it."
Dean frowned. Cas normally wouldn't have willingly admitted that middle bit.
"Good to know. Why were you being chased by a demon?"
"I was looking for something and stumbled across the demon."
Dean pulled Cas to his feet and throwing one of the angels' arms around his shoulders helped him into the kitchen. Cas would be fine in a few hours, being an angel helped with that, but that didn't mean that he wasn't currently hurting.
"What were you looking for?"
"Something from my last time on Earth."
Dean helped Cas into a chair in the kitchen and then moved to shove his food back in the oven for a bit. He frowned at the angel and grabbed another beer.
"When was the last time you were on Earth?"
The angel just shrugged.
"The civil war had just ended."
Dean spat out his beer.
"That's a couple of hundred years ago."
