Prologue
"Gabriel, what's wrong with Castiel?" Michael asked, watching his younger brother with concern.
"No idea. Ever since your wedding, he's been kind of mopey." Gabriel sighed. "I don't know what to do."
Michael thought for a minute. "I think I have an idea."
He flew over to Cupid's office, the interior decorated in pink and read hearts. Michael looked around for the love angel, and, not seeing him, opened the file cabinet drawer marked 'Angel's Mates'. He flipped through the papers, looking for Castiel's name. "Aha!" He smiled, taking not only Castiel's but Gabriel's as well.
"What are you doing?" Gabriel asked suspiciously.
"Nothing." Michael tucked the papers in his pants pocket. "Don't worry about it, little brother."
Gabriel frowned, hating to be left out of things. "Michael, tell me."
"Don't say a word to Dad or Cupid. I'm going to find Castiel's mate."
The fun-loving archangel's face lit up. "You're gonna need help. No offense, but I'm a pretty good match-finder."
"Fine." Michael reluctantly agreed.
"So, Mike, how was the honeymoon?" Gabriel waggled his eyebrows, grinning. "Where are we going?"
"I'm going to back to New Orleans."

Castiel was extremely happy for his brother and for the Winchesters, but there was a deep sadness in his chest he couldn't let go. If Cas was going to be honest with himself, he was a little jealous. Sam had a wife and two kids to go home to, to help him with his troubles; Dean had a sassy, spunky girlfriend who understood Dean more than Dean understood Dean; Michael had someone who instilled a love for most of humanity in him and changed the oldest archangel for the better. Castiel had nobody. He pulled his knees to his chest, watching the people below.
If only he could've found out who his soul mate was when he went looking for the Winchesters', but God had told them to not break into Cupid's office again, and there was no way the love angel would tell Cas anything. He looked over to see Michael and Gabriel talking, probably about archangel duties. Then, Cas heard the prayer of his favorite human. "Cas, got your ears on? We need you."
He smiled slightly. He was wrong. He had Dean.
