(You and Nathan are friends since childhood,you were there for him in anyway possible).

after a failed Treasure hunt Nathan and you got into a heated argument that was the very first time in you're both's friendship, you both yelled at each other...and Sully (your father) and Sam (Nathan's older brother) stood there holding both of you apart.

"Just tell me, Nathan. Because I'm curious! Why do you think Elena is interested, huh? Do you think, for one minute, that she would even be with you if you weren't the infamous Nathan Drake you are. Are you blind?!"

You said with a clear pissed tone.

Nathan:"At least she treats me like I'm somebody!"

Nathan yells at you.

"Yeah, well would she love you if you were a nobody?"

You yelled back and then he snapped at you.

Nathan:"NOBODY LOVED ME WHEN I WAS A NOBODY!"

he turned around not facing you, you had enough.

"I DID!"

He was shocked and froze...and turned around to look at you...

Nathan:"What?"
