Dean was off celebrating with Sam while Castiel returned the does to their pen. He heard a sound, a kind of shuffling from behind him. He turned around and gasped as his eyes landed on a most strange sight he'd ever witnessed. Gabriel, wearing a suit, sitting on an all black unicorn. "Gabriel!" Castiel said angrily. "Get down." He ordered. Gabriel laughed and hopped down. Castiel hurried over and began inspecting the unicorn for any injury or blemish. It was perfect.

"From me and dad." Gabriel said happily clapping the creature on the shoulder.

"Be gentle." Castiel huffed.

"You mean from you." Said an all too familiar voice. Castiel turned to Dean with a sheepish smile. "The unicorn. Daddy dearest didn't have anything to do with it did he?" Dean continued as he made his way over to Castiel. Gabriel laughed and nodded.

"I guess." Gabriel said. "So you must be Dean." He said offering his hand.

"Yeah, and you must be Gabe." He responded with a gruff handshake.

"You're the fag dating my baby bro." Gabriel said pulling his hand away.

"Gabriel!" Castiel gasped.

"Yes." Dean said.

"I can say that because I'm one too." Gabriel said grinning and winking at Cas. Castiel frowned at his brother but said no more.

"Come on. Let's head into the castle." Dean said slipping his hand into Castiel's.

"Ahhh yes celebration." Gabriel purred. "And you can introduce me to today's victor." Gabriel said grinning and slipping a hand into Castiel's unoccupied one.

"You two go ahead. I'll just put this unicorn up in a pen." Castiel said slipping his hands out of theirs and resting them on the beautiful creature. "He's beautiful." Castiel added smiling at the two of them.

"I didn't know there were black unicorns." Dean commented.

"They're very rare and not like normal unicorns." Castiel said. Dean smiled; Castiel came alive when he was talking about his subject. Dean loved this side of Cas. "They're more powerful in strength. They're stronger, faster, more rare, and harder to catch. It's impossible to catch one without damaging it, but this one's in perfect condition." Castiel said in awe.

"Well I've been working on an expedition studying unicorn habitats." Gabriel said smiling.

"Yes, I read the book written on the project." Castiel said nodding. "They go around to abandoned spots, herds of white unicorns have inhabited. A few of them had been re-inhabited by black unicorns. They travel in herds of about four mares and one stallion." Castiel explained for Dean's benefit. "But how did you manage to catch one?" Castiel asked turning to Gabriel once more.

"We are forbidden from helping them in case of danger so, although it broke our hearts, we could not protect them from the arachnid onslaught. This one fled to our camp for safety." Gabriel said smiling at the big black brute.

"The others, it's herd, they were all-?" Castiel asked. Gabriel nodded sadly. Castiel pulled out his wand and put together a pen for it quickly. When it was done and the unicorn had been put safely inside it, the three went into the castle.

"So, how is it?" Gabriel asked looking pointedly at Dean.

"How's what?" Dean asked. Castiel didn't like being in the middle, he didn't like the way they were talking around him.

"Shagging my baby bro?" Gabriel responded casually. Castiel felt his face burn in embarrassment. Dean looked between the two brothers before his eyes came to land on Gabriel.

"If you're asking how he is in bed then you're a perv but he's great." Dean responded. Castiel noted the lie; they had not yet had sex, so it was not something Dean would know.

"No Dean-o you little perv. I was asking how you like fucking a guy, someone who has a big bro. You're a big brother too, are you not?" Gabriel said grinning.

"You're fucked up. You know that?" Dean huffed before slipping a hand into Castiel's and dragging him off to sit for dinner. They had missed half of the dinner but it was no matter. They sat with Sam, Pam, Jo and Ash. Ash worked in intelligence for Aurors, keeping information on any targets or enemies. Ash worked with Jo's mom Ellen, Dean, he had worked with both of the deceased Winchesters, and Bobby. Bobby, Dean's uncle, had practically raised the two boys when their parents died. Gabriel had taken a seat at the head table, near Castiel. Gabriel was sitting next to Castiel who was next to Dean who was next to Sam. Across from Sam was Ash, his fellow Ravenclaw. Jo sat in front of Dean and between Pam and Ash. Pam was in front of Castiel, something that made him only slightly uncomfortable.

"So who's the new guy?" Jo asked eyeing Gabriel skeptically.

"This is my brother Gabriel." Castiel said smiling at his brother proudly as if he were showing off an award he'd won.

"Aren't you just a doll." Pam purred.

"I don't like him." Jo said frowning.

"Wake me if something interesting happens." Ash said putting his head down on the table.

"Hi, I'm Sam. Nice to meet you." Sam said smiling over at Gabriel. Gabriel's eyes lit up like he'd just spied candy, something he was particularly fond of.

"Well hello there." Gabriel said as he moved from his seat to sit next to Sam. "It's a pleasure." Gabriel purred.

"Well this should be interesting." Dean mumbled to Castiel.
