Nico
Nico strolled up towards the motel room door in Salvation. His hair had finally gone back to it's normal black, and Anna had lifted the curse on his clothing when he'd seen her a few months earlier, leaving him in his comfortable uniform of all black and his aviator jacket. The large hellhound panted by his side. He patted her head softly.
"Stay Mrs. O'Leary." She woofed as softly as a tank sized dog could. It rumbled like a thunderclap. Nico smirked and wandered over to the door. He could make out the raised voices of two men inside. Nico's smile slipped a little. He remembered fighting with Bianca like that, once upon a time. Then Nico swallowed harder. The elder brother's aura smelled of the condemned. He was going to die at some point in the near future.
Although, he'd seen the same thing around Dianne when her quest had first started, and she was still alive and kicking a year later. He knocked on the door. A few seconds later it opened a crack, an attractive man with dark blonde hair peering through the opening. Nico waved at Dean Winchester's suspicious face.
"Don't shoot. I'm a friendly!" He deadpanned. Dean's mouth tightened as he unchained and opened the door.
"What are you doing here kid?" He asked locking the door behind Nico. Nico raised his eyebrows.
"You called the number Blu left you right? The emergency line?" Sam looked at Dean.
"Blue?" Dean asked cautiously. Nico huffed. Mortals.
'No, not just mortals. Mortal hunters.'
Nico reminded himself to be careful even as he smirked.
"Blu is Anna, my sister." Dean nodded slowly.
"So why are you here?" He asked harshly. Nico gave him a duh look.
"I'm the cavalry. We don't have time to waste. We need to head to South Dakota." Nico walked back to the door and opened it wide, gesturing for them to follow him.
"Look, kid. You can't be the cavalry. It's to dangerous, and you're what, 16, 17? Just no. we have a demon to kill" Sam shook his head, all of his patience gone. The technically eighty-eight year old son of Hades allowed the age comment to slide, but he wouldn't forgive the lack of confidence in his skills. Nico let some of his inner darkness out, the part of him he usually kept tamped down. Even Dean suddenly looked a little afraid.
"You're useless dead. And that's what you will be if you don't listen to me. Trust that Blu's got it right. This ain't my first rodeo, and it sure as Hades won't be my last. Now let's go. Blu is on her way, she'll meet us there."
