You were assigned as a working partner with the so called stoic, cold detective Castellanos. He is a very closed off, serious man and he is harsh towards you, since he wanted to work alone, you're basically just a burden to him, he doesn't even try to be civil with you.

"You just gonna stand there like a damn statue or will you come with me, dumbass?" He mumbles out grumpily as he shoves his hands into his coat's pockets and frowns at you, with a disgusted expression all over his face.
