Remus couldn't believe it.
It couldn't be true.
No matter what anyone said, they couldn't be dead, especially not at the hands of Sirius.
It must be some sort of tale to keep Harry safe.
Sirius loved James like a brother, Lily like a sister, and Harry like a son.
There is absolutely no way he could have lead Voldemort to them.
And no matter how much Sirius had picked on Peter, there is no way that Sirius would've killed him in cold blood, no matter what the eye witnesses said. They were muggles after all, nothing against them, but they couldn't be held reliable witnesses to something they didn't even know existed.
But… If it was true, or even if it wasn't, Remus was all alone now. Sirius was the secret keeper, there is no other way Voldemort could've got to them.
Remus suddenly couldn't breathe.
His pack was gone. James, Lily, Peter, Harry… Sirius, even if it was in a different way. Remus was totally alone. He had other friends, but he didn't have a family like them anymore. He was alone.
How could he stand to be alone again? He hadn't been alone since his first year at Hogwarts, hadn't been alone on full moons since his fifth. He didn't know what it felt like not to have someone to keep the wolf from killing him.
And suddenly letting the wolf take over wasn't such a bad idea.
What is the point if he was all alone? Who was he protecting? Himself? He was already in pain, already wounded, even if not in the most visible ways.
Remus closed his eyes.
"I'm sorry, James, Lily, Peter, Harry, for not protecting you. I'm sorry, Sirius, for letting you slip into what you always hated."
Remus felt himself starting to cry.
"And I'm sorry to all of you that I can't manage to keep living for all of you. I'm not strong enough to be alone."
Remus picked up his wand and turned it towards himself.
Knock.
"REMUS! REMUS! It's Helga! It's Harry! You won't believe it, he's alive!"
Remus froze.
"A-alive?"
He dropped his wand, opened the door, and collapsed into his waiting friend's arms.
