Sidonie putting the peers of the realm (including Barquiel L'Envers) to shame after Barquiel challenges the still-injured Imriel to a duel and accuses him of treason. She downright states that no-one rises to power with an unblemished heritage (and basically accuses all the men there of hypocrisy) and bluntly voices what everyone had been too afraid to say— that L'Envers had previously framed Imriel for treason and smeared his reputation and that the only reason Imriel could have been suspected for any sort of treason was because L'Envers had put it there.
