Marco stood outside of Singer Salvage, waiting for the lights to go out.

He never liked theses hits, but this what the boss wanted.

Dick Roman wanted Crolweys business out of the way, but the pompous bastard took everything that Roman threw at him and threw it back tenfold. Roman decided to send Crowley a message, int eh word of Bobby Singer.

Marco thought it was weird that Crowley, who seemed very high class, is involved with a grungy, gruff mechanic. But he supposed he's just slumming. What really bothers him is the scent.

Marco is a lausenschlange and he smells the scent on Crowley. He smells like a feline wesen, but he wonders why the scent isn't so strong.

His thoughts came back to the present as the lights turned off. He let out a breath, psyching himself up.

He quickly picked the lock and stepped inside, taking his gun out. As he walked into the living room, he heard the sound of a gun being cocked.

"Stay where you are, idjit."

Marco chuckled lightly and turned around, seeing Bobby holding up a shotgun.

"It's nothing personal, . It's just business." Brady said, his skin rippling as he woged, hissing at Bobby, expecting him to scream and run away. But the older man just chuckled.

"A lausenschlange, eh?"

Marco woged back, not understanding until he caught Bobbys scent.

It was feline, with a hint of poison.

It's Bobby, he's wesen.

Before Marco could think, Bobby woged, his face turning into a lion and he growled as he tackled him to the wall. He roared in his face as a scorpion tail came into view, the tail hanging over him threateningly until it plunged into his chest.

As the poison took over Marco's body, the last thing he thought of was that Dick Roman was fucked.

AN: Grimm AU!

I thought hard about this, but I could totally see Bobby as a manticore, that would just be so awesome. Crowley is human and is involved in shady business, of course. Marco si just some random dude I had to kill off.

Next is Domestic AU!

I don't own SPN or Grimm! Enjoy and comments are loved!
