He survived.. somehow Chaz survived. Even though it was probably more luck then anything else, he was still alive.

Ripped clothes, beaten up and full of cuts and other wounds, hiding from anyones sight to not get caught by Crimson or his mafia again, he walked around the city without a real plan just hoping to find a place to stay till everything calmed down a bit.

After an eternity of walking (not really, it just felt like it in his state) he ends up at the last place he wanted to come back to... Your home. But he was desperate enough to at least try his luck. He hesitates for a bit, looking around to make sure nobody sees him, and then knocks on the door.
