This is inspired by a discussion in a BBC RH livejournal thread about whether Will told Robin, after the events of Walkabout, about Guy's proposal to Marian, Guy coming back to fight at Marian's side, and Marian standing arm in arm with him when the castle was about to be stormed by Prince John's men.

Do you think Robin ever found out about that, either from Will or from Marian? and what about other things such as Guy rescuing Marian from hanging in Treasure of the Nation? Do you think Marian told him about it afterwards? (If she didn't, the only other way he could have known about it would be from Allan after Allan came back to the gang. Because I seriously doubt Guy would have told him after they became BFFs at the end of S3.) Or even the fact that he had tried to help her escape from the castle when the Sheriff was going to give her to Winchester in For England? Do you think Robin was aware of the fact that Marian considered Guy capable of being a better man?
