Family #78900 Jewish family

[AskSatanOperator]

Hello family, not long ago I found out that a relative of mine is Jewish. He's not that close to me, but I can see him often when I visit other people. He's still a child and is Jewish on his mother's side. What I'm getting at is, what should one do if it's inevitable not to see him? I'm also curious if a Zevist has a son who is Jewish, how should I proceed?
