What should i do??? 10 points?

well my name is billy, and just the other day i was hired a position at a mental institution in van buren and my boss and i met up at his place to talk and such when i found some files on his desk that i'm pretty sure had his face on it. i was scared and i didn't know what to do so i just ditched him. when he got out of the bathroom i left so since then he tried calling me. i finally picked up and now he wants to meet up at my place this time. what should i do? i wanna ask him about the fils but i'm too scared. should i kill him or something? what should i do guys?!
