Jake didn't let a whole lot of stuff get to him. He promised himself as a kid that he wouldn't let anyone or anything hurt him. He had to watch out for himself, and his mother. No one else mattered, he couldn't let others matter.

He met you on a mission, and he ended up keeping contact with you. He didn't consider you a friend. He didn't want to have to worry about you. He'd watch your back if he had the time, otherwise, he kept to himself.

Then his mother died. And suddenly he was alone. At this point, she's been dead for a few days and the truth was, he hadn't left bed since paramedics got her. He didn't know how to put together a funeral. Or if he should, there would be no one to come to it. Not to mention the cost.

He was still in bed at the moment. He should have felt alarmed when he heard his front door open, but he wasn't sure he had the energy to. He was so tired.
