Nick looked up when he heard the light footsteps. He took a deep breath and moved around to look up at Natalie.
The Wesen stared at him without any expression besides a rhythmically twitch in her cheek.
"I'm sorry about your loss", Nick said finally after the silence between them lasted too long.
Natalie continued staring down at him.
Nick sighed. "Look, I will give you a call whenever I will find something and can lay my hand on it. We will catch this bastard, I promise."
Natalie looked over to Hank's empty chair and suddenly Nick got a real bad feeling.
"Nick?" Captain Renard said, coming over to his working place.
Nick still watched Natalie suspiciously but nodded. "Sir?"
"In this case we will unite with the FBI", Renard said to him. "You will team up with Agent Furlong."
"What?" Nick moved around and stared at Natalie. "No way!"
"Nick, that's an order", Renard said vividly.
Now it was one of Nick's cheek-muscles twitching. "Sir, she is too close!"
"I am the agent investigating this case", Natalie declared in this moment, moved her head and looked at Nick very seriously. "It's a serial killer active all around the states. Now he's here in Portland, I expected him to be in Seattle. That's why I was here this fast."
Nick began to understand. "This murderer is up against ... ?"
Natalie only nodded and Nick realized the truth:
The murderer of Caroline Witten was up against Wesen!
