Do I tell him?

[Tangled Web]

IMO I would tell him very gently if the conversation came up. I wouldn't be the one to just jump out and tell him but if he was talking about it and telling you things that he thinks is accurate and you know differently, I think it would be a good idea to say something about it. And maybe tell him that when the others are ready to let themselves known to you, they will. Let him digest things after he knows what you know. I would want to know if someone knew those things about me instead of believing things that weren't true. But that is just me. Or maybe just ask him what he wants you to do with the information you have the next time it comes up in conversation, maybe he just wants to find out things in his own time.......BUT if you ask him that way he will have more control and a say in what he wants to know and what he doesn't and won't feel like you are keeping things from him.
