Sarah and Oliver weren't the only ones who went through hell. Laurel has a secret about where exactly she was the first year her sister and boyfriend were missing. She's never thought much about that time since mainly it involved a demon named Ruby. And yes, she was possessed.

Charlie's dead and Dean's missing. Sam needs to find him but doesn't know how. So he calls the woman his brother told him about, Felicity Smoak. Rated M just in case

Felicity grew up with the Winchester's and Harvelles but she was the only one who ever got out. But you're never really out are you? Ghouls are terrorizing Starling City so she calls Sam and Dean and introduces them to Team Arrow. Oliver thought he had enough on his plate but now Monsters are real. Dean/Jo Olicity.

In this Story Felicity is the hero. She has a Supernatural secret, witch could change her relationship with Team Arrow forever, and the fact that there are others out there who also know her secret only complicates things. Rated M for later Chapters

They've gone up against some pretty Big Bads before, but when Felicity accidentally gets in the middle of a fight with a vampire, Team Arrow's lives get a whole lot weirder. The Winchester's had two goals when they got to Starling City: One, kill the vampire that had left a slew of bodies behind. And two, stay off The Arrow's radar. Well, one goal accomplished is better than none.

ONE-SHOT: It's time to get even. And Dean is up first. Sequel to Charlie Bradbury Meets Felicity Smoak, where the Winchesters play a prank on the two ladies.

ONE-SHOT: Good crossover fun. Charlie Bradbury(Supernatural) meets Felicity Smoak(Arrow).

Fifth Arrow/SPN Crossover: - Sam gets a late night call from a desperate Felicity informing him of Oliver's trip to face Ra's al Ghul. She's not willing to stand by and let Oliver go by himself and Dig is standing firm on following Oliver's orders, Roy's not skilled enough so that leaves Oliver's last to allies, The Boys.

Fourth Arrow/SPN Crossover: I am throwing in the Flash for fun. Ghosts appear in Starling City, Oliver calls in the experts. Sam and Dean figure out fairly quickly someone is summoning them. When the boys and Team Arrow follow all the trails and track down the summoner they come up against a problem and the solution is going to require a little extra speed.

This is his life now. If he's not out getting his vigilante on, you can usually find Dean Winchester either having a tea party or playing space cowboys with his girls. Tonight he did both. This is definitely not where he thought he would end up. (A Daddy!Dean/Mommy!Laurel fic for anonymous on Tumblr.)
