息子さん『も』誰『も』来なくなっちゃいましたね
Even your son who… then something about coming.
Not too sure on how to parse this one. いました+ね at the end I imagine.
Actually 来 doesn’t have a definition « to come » so it’s different than Chinese. It’s a prefix which means “next”.
来なくなっちゃ that I’d need help with. I’ve never seen a っ before a ち so maybe it’s a つ?
