A heavy silence fell over the room as the two friends sat, regarding one another.
Remus held Sirius's gaze as he flashed between anger, confusion, and grief—trying to focus
on not letting his emotions get the better of him.
He tried not to take his fury out on his friend. Remus had been there during the
moments of Sirius's life when he had lost people: his father and brother, James's parents.
Though Remus had not been there the night James and Lily were killed, Sirius knew that
he understood well enough to know that it took a thing like death to bring him to tears,
however angrily he fought them off.
"Who?" Sirius finally broke the silence, the word pushing through his teeth on the
edge of a low growl.
"Snape," Remus said quickly.
"Are you fucking kidding me?!" Sirius stood up and kicked the nearby table hard
enough that it flipped over, knocking the teacups to the ground. He staggered briefly, trying
to establish balance, his strength still greatly lacking. "I knew it! I told you! I told all of you
that we couldn't trust that snivelling traitor!"
"Well, you'll have a lot of time to say 'I told you so,' but it won't do a bloody thing
to change what's already happened." Remus moved from his seat, flicking his wand to
repair the damage Sirius had caused.
As the two men stood face-to-face, Sirius looked into Remus's eyes belligerently.
His friend had a good four or five inches on him and was clearly using that leverage to get
Sirius to calm down and return to his seat on the sofa.
"Dumbledore's dead, Grimmauld Place is compromised, Snape's a traitor,
Voldemort is infiltrating the Ministry, and Harry's in danger. He's always in danger," Remus
said, taking a step forward and forcing Sirius back.
The friends growled at one another, their canine and lupine counterparts vying
equally for territory. Sirius's nose twitched, and he let out a low, dog-like whine when
Remus growled louder and stepped forward again, invading his space. When a sharp pain
stung his shoulder—a magical reminder of his place when it came to the old game of
werewolf versus Animagus—Sirius finally backed down, and he collapsed on the sofa
behind him, unable to stand any longer.
