(OOC: What do you think of Snape telling everyone about Lupin)
[OOC: Severus has done some fucked up things. But that was completely justified! Lupin forgot to take his potion, and then students were put in danger.
There is some trauma here. Iāll address that first. Severus was almost killed by Lupin when he was a child and then blackmailed into keeping the secret.Ā
His life was, in his eyes, worth less than Lupinās secret to Dumbledore. And, if he WAS killed, Dumbledore would have still kept things under wraps. So he probably isnāt wrong. Now, a similar situation comes up, but he has power. Of course heās doing something about the situation. Iād be more surprised if someone didnāt.
But taking out the trauma element, this decision was STILL justified! Think about it this way. Remus forgot to take it once because something important came up. And then students almost get killed. Dumbledore does NOTHING!
Students almost died because their professor forgot to take a potion on time. Does Dumbledore make arrangements to prevent this? Of course not. Heās Dumbledore.Ā
You know the secret. You KEPT it for about 18(SiriusāĀ āprankā happened in fifth year, before SWM. Makes SWM a lot more fucked up, but separate thing) years.
Now, students were put in danger. Dumbledore wonāt do shit. What do you do? Do you keep it and hope this doesnāt happen again? No, because if this happened once, it could happen again. And you might not be able to put yourself between your students and a bloodthirsty creature. Students could die. It would be on you.
You tell the secret! Because that is the only thing you CAN do in this situation. If you donāt, students will probably die.
Dumbledore doesnāt seem to feel like this was an issue, so doing nothing isnāt an option. You could talk to Dumbledore or your coworkers about it, but Dumbledore has shown he doesnāt care and your coworkers are much closer to him and probably wonāt do anything either.
So telling the secret to the students is the only thing you can do to keep them safe.
Yes, this had consequences for Lupin and Severus may have enjoyed it. I donāt blame him for that. But that doesnāt change the fact that even if he did it out of spite and nothing more, which I doubt, the decision still would have been the best one objectively(at least in my opinion. If you want to DM me, we can discuss this further)
