I think she might have told him the whole story - we just didn't see it. Obviously by the fact that they kept moving places there we didn't see every second of the conversation. While I would have liked to have seen it, I suppose they were thinking 'Well, the audience already knows all this, they won't want to basically hear a rehash of it.'
Obviously if it comes out he doesn't know about Sharon, then I'm wrong, lol, but yeah, I think she did tell him.
