Nick was a scammer. He knew it was wrong, but you gotta do what you gotta do. Because surviving was rough. Especially for shapeshifters, like him.

So when you convinced him (blackmailed him) into helping you with a case, he didn't have much option.

So when your suspect disappeared after attacking both of you, and your chief tried to kick you out, he was the one to defend you.

You were quiet in the car, and thanked him softly. He sighed.

"Never let them see that they get to you."
