So I decided to write this after watching 2x01, there's no specific mention of any events from that episode, so you should be safe to read this if you haven't seen it yet :)

Richie tightened his grip around the man's neck, ignoring the way the skin bunch up beneath his fingers, and the man's face turned a dangerous shade of red. He spared a look back at Santanico who still had her back to him.

"You okay?" he called.

She turned around, wiping the blood from her lip with her thumb. "I'm fine."

As he looked back at the man, Richie released his grip, letting him fall back a few steps. Richie watched as he coughed and spluttered everywhere. He was supposed to be an easy mark, just for a quick feed, but something had gone wrong. It didn't matter how. All that mattered was that their dinner was still breathing, and Santanico was pissed, even if she was putting on a scared, innocent look for show.

Suddenly the man laughed. Richie could feel the growl in the back of his throat before it was released. He grabbed the man, but this time he didn't hold him. Instead Richie shoved him hard against the nearest wall, watching as the breath seemed to be knocked out of him.

The man managed a laugh. "So you're pissed I hit that hot piece of ass."

Richie made a face like he was contemplating that.

"You're going to wish you'd finished the job before."

Richie almost rolled his eyes as the man brought out the gun he had been keeping tucked in the waistband of his jeans. With the gun pointed straight at Richie's head, the smug look on the man's face only grew.

"Any last words?"

"I'm not the one you should be worried about."

Richie titled his head to the side, revealing Santanico. She gave the man a sweet smile, even tilting her head to the side in an innocent gesture.

"Her?"

The man started to laugh, but it caught in his throat as Santanico's eyes changed colour. As her fangs extended, her jaw opened wide, and her skin began to change. Seeing the true Culebra that she was, the man's hand began to lower. His mouth was still open mid laugh, but his eyes were now wide with terror.

"What the-"

Santanico launched forward effectively cutting the man off. Richie had leaned to the side enough to let her by, and was now straightening himself up. He adjusted his suit jacket and tie with one hand as he watched Santanico sink her teeth into the man's neck. He watched her for a moment before walking other. The man looked at him pleadingly, but Richie ignored it. Instead he tangled his hand in Santanico's hair, before leaning down and biting the other side of the man's neck.

Eventually, when they were almost full, and the man was nearly drained, Santanico and Richie shared a knowing look. They both, in sync, pulled away from the man, fangs still bared. Before he could fall out of their grip, the pair bit down hard one last time and both tore out a chunk of flesh, effectively ending the man's life.

Licking their lips, and returning to their human forms, Santanico sauntered towards Richie. She lifted her head slightly, and smiled just before their lips met.
