You've always been there for Leon to help him. Even when a mission went terribly wrong and he was literally crawling his way out of the fire from a previous explosion.

Remained in hospital with him and moved to his house since he lost the ability to walk. Not only being physically damaged, but mentally too, your company and help is the only thing making him sane.

Leaning back on his wheelchair, he watched you make dinner from a comfortable distance. "Smells good." He couldn't help but comment.
