They had hardly heard the police car sirens before the door to their motel room was burst open and several police officers surrounded them. The two brothers had no choice but to raise their hands in surrender, knowing they were completely outnumbered and they didn't have a single weapon in arms reach. But Dean managed to catch Cas' eye, who was still standing outside as the cops appeared to have not noticed him and he signalled for him to get the hell out of here. The angel understood instantly and once Dean blinked, he was gone.

"Sam and Dean Winchester, you are under arrest for several accounts of murder, impersonating FBI agents and most recently, your suspected connection to the murder of Sophia Cooper"

Sam and Dean almost completely ignored the officers as they read them their 'rights', handcuffed them both, and dragged them to the police cars. Instead they looked to each other, communicating silently like they always did as children in the backseats of the Impala when their dad had told them to be quiet. And thanks to all the practice they had as children and just that extra level of connection they both knew they shared, the brothers had managed to formulate a plan even before the police car door slammed shut in Sam's face.

"Are you sure this is a good idea, Nick?"

The Grimm smiled at the worried tone of Monroe's voice. They finally had the Winchester brothers under lock and key and Nick was desperate to find out who (or what) they were. However, Hank and Monroe weren't so sure of his plan.

"So, you're planning to go in there alone with an all-round criminal, murdering machine, you're going to try and provoke him and make him angry to see what kind of Wesen he is when we don't even know if he actually is any kind of Wesen at all?"

"You said so yourself, something is off about these guys. Wesen or not, I have to check it out. I'm sure I can look after myself" Nick added the last part to try and lighten the mood, but apparently it wasn't working.

"Fine, but be careful"

"When am I ever anything but careful?" Nick smirked before entering into one of the interrogation rooms where Dean Winchester was sat.

"Why does it make me more nervous when he says stuff like that?" Hank sighed before he and Monroe took their places behind the double-sided mirror to watch the events unfold.

Nick looked across the room at Dean. He was tall, but short compared to his brother. He sat with his right hand cuffed to the table, smiling smugly up at Nick. The Grimm sighed- this was going to take some serious work to crack this guy.

"Dude, no offence but you guys are in way over your heads" Dean's eyes followed Nick as he walked across the room and sat in the chair opposite him.

"No, I don't think I am. I've dealt with people like you before, if you know what I mean" Nick glanced over at Dean.

"Oh no, I really don't think you have"

Nick simply smiled to himself before standing again.

"I feel sorry for you, I really do. I mean to lose your mother so young and then lose your father too; it must have really screwed you over. That's what started it, isn't it? The loss? And you and your twisted brother seem to find some comfort in murdering the innocent"

"Believe me, these people are anything but innocent"

"Okay, let's say that's true" Nick began to pace slowly up and down the side of the room "Let's say you and your brother are on some twisted path to save the world from all the evil to exist. How many innocent die in the crossfire? How many innocent, defenceless people have their lives snatched away because of your selfish actions" the Grimm cast a glance over to the older Winchester and, to his surprise, the guy had his eyes cast down to the table and the slightest flicker of guilt on his face. Nick continued with the taunting, but somehow it all felt slightly wrong. This guy wasn't Wesen, he was almost certain of that. But he wasn't any common killer either. Dean Winchester was something new.

"I can see it Dean, I can see it in your eyes. You truly believe you're a righteous man, keeping the world from harm. But what about those who lose their lives because you were too busy working for the 'Greater Good'? Your family got caught in that crossfire, didn't they? Your mother, your father. Friends have been lost in that crossfire too; Robert Singer, Ellen and Joanna Harvelle, and so many other innocent people I doubt you even know the names of"

"How do you know about those people?" Dean glared up at Nick, his eyes darken with rage. He was obviously emotional yet Nick saw no sign of him beginning to Woge. But he knew he couldn't just leave, Dean was about to crack and Nick needed to know the truth behind who this guy really was.

"We know a lot about you, all the people you've lost in your crusade. They were good people Dean, were they really worth losing for... what? Revenge? Justice? Enjoyment?" Nick smirked down at Dean slightly. He had figured out that shouting at the guy simply wouldn't work like it did with most people. Taunting him and showing him that he was powerless; that was the way to getting him to burst.

"Look, I don't know or care who you are or what you know or don't know about me. But let me give you some advice, don't make me angry" Nick looked over to see Dean's eye cast down to the ground, his fist clenched and his left hand tightly gripping his right forearm.

"You claim you are murdering the evil and saving the innocent. But do you know how I see it? I see that you're murdering the innocent, more innocent died in the crossfire, and you and your brother, you two are the evil ones"

"Don't do this" Dean practically growled.

"Why?" Nick placed his hands on the other side of the table to Dean, bearing down on him. When Dean didn't answer, Nick finally said what he knew he had needed to say the whole time; the final thing to make Dean crack.

"Poor Sam, having his life ripped apart by his father as a child, and now by you. He could have had a chance at a normal happy life, but you just had to go in there and screw everything up for him, didn't you? He resents you, he must do. You turned that innocent boy into a monster, just like yourself. You ruined little Sammy's life"

Silence followed for roughly ten seconds before something happened that surprised and confused Nick to no end. Dean stood up with his hands balled into fists and his eyes burning with anger. With one swift tug of his arm, he wrenched the handcuffs off the table. Nick stood there for a moment in complete shock, which was his fatal mistake. Dean took the opening and charged at him. He grabbed his wrists and pinned him to the wall before throwing him across the room. Nick was slammed into the table and soon Dean was on top of him. The Grimm's instincts took over and grabbed Dean's hands before he could punch him. They stayed there for a moment struggling; Dean pushing himself down onto Nick and Nick pushing back whilst holding his wrists to try and stop him moving. The Grimm's head was spinning after hitting his head hard on the table. Blood was rushing in his ears and his vision blurred. The grip he had on Dean's wrists loosened but no more punches came. Nick could vaguely hear Monroe's voice before he slumped down over the table and lost consciousness.
