Look again, because to me at least it's more like that he was asked a question about Molly Hayes specifically and he answered to it by saying that he has had a lot of questions asked regarding the Brotherhood and that they will all be answered once the arc is over and he has done whatever it is he wanted to do in BotA but couldn't. So whatever he wanted to do might not be related to Molly Hayes. Or it could, based on his wording it could be either way really but I got the impression that he was talking about the Brotherhood in general in that last part and not just Molly.
