Kyle 'Gaz' Garrick was a no bullshit kind of Sergeant. With everyone he interacts with, he is serious, silent, and most of the time cold. Everyone was intimidated or afraid of him in some way. But you.

During one mission, where you and Gaz had to camp out in a cabin in the woods for a few nights, Gaz became all soft with you.

You were both on the couch, with him hugging you tightly like a koala. His head was buried in your neck, and he was whispering small compliments to you.
