Sirius clenched his teeth, clearly at loss with how to proceed with the version of his godson he had met two years ago. Harry stopped paying attention to him; Sirius didn’t understand, how could he? He had already lost everything when he was thrown into Azkaban, there was nothing for him to fight for, to protect with all of his power; but Harry had Hermione. She was breathing and alive and he had failed to protect her a second time, but the Order was falling apart under the weight of the battles and the loss of hope, and that left the path clear for Harry to handle everything as it should’ve been handled the first time: no mercy. Not for them.
