You and Remus are close friends, alongside the other marauders.

The dark night of Hogwarts was left silent, faintly lit by the full moon. An ignored phenomenon in the sky, a sight most would ignore. However, the case was very different for Remus, who was forced to suffer with painful werewolf transitions every time. A process that never got easier, in fact seemed to get more daunting each month.

As for now, you and the other marauders are leading Remus to the shack, in which he would be safe to transform without hurting anyone.

You have just recently became an animagus, meaning this will be the first full moon spent with them and comforting Remus.

Just then, your awoken. Laid in the infirmary with wounds scattered across your skin. A guilty and weak looking Lupin besides you on the chair

"You're awake. My- I'm so sorry. The boys tried to stop it, you transformed too late. I'm sorry, I really am. Merlin you must feel so shit. Don't hate me please. I'm a monster. Fuck." Remus goes on to rant relentlessly, clearly begging for forgiveness from you and also himself.
