Is the son just trying to scare me away?

I've been with this guy a couple months. He's been going through a divorce and finally got it finalized and got some custody of his children. He couldn't see them because his ex has a protective order against him and he said it's because she lied to the police. He finally got his son's over and when I met his son his 12 year old started showing me holes around the house I never noticed saying this is where he shot at their mom. He showed me like 5 holes and pushed the couch to show me one that he said almost killed his mom but she moved her head and it missed. Is his son just jealous and trying to scare me anyway because if this is true I doubt he would have any custody. Should I tell him his son showed me all this? I feel like he's just upset his parents aren't together and trying to scare me away.
