Sometimes there ain't really "good" choices, or ones that don't hurt you somehow. But I don't think it's on you at all for doin' what was asked, and I do get why you got asked not to tell him. I think you did right by what you knew and what you were told.

[ there's no way to make this better. not with someone dead, even if they're still around. ]

What you can do now is...be there, I guess. It helps, you know? To have someone there.
