Wormtail
This never was supposed to happen. Really, it wasn't. I didn't want anyone to die. But I was not brave like James and Sirius and Remus and Lily and even Harry. I don't know why I was a Gryffindor. I always hated being expected to be strong.
I'm weak.
When the Death Eaters threatened me, I never thought I would be to only one to give in. Wouldn't anyone make a sacrifice to save their own life? I expected Sirius and Remus to join, too. I swear I did. Then we would all be allies. When I found out they hadn't—I had no choice but to decide who I wanted to be loyal to. I hated having to make that decision, I always hate being put on the spot, but I chose the only people I could choose. I chose the people who would have killed me if I'd chosen otherwise.
I never voluntarily gave James and Lily and Harry up. I swear.
The Dark Lord summoned me to him. He had gotten word that the Potters suspected one of their friends was a spy.
"Who do they suspect?" he demanded of me.
Lies are useless against the Dark Lord. He sees through them and he will punish you for them. You have not choice but to tell him the truth.
"They suspect Lupin. Remus Lupin."
"The werewolf who refused us."
"Yes."
"Excellent… And you are their Secret Keeper?"
What could I say?
I couldn't lie! He would have known! He would have killed me!
I had no choice— It was all I could do— I'll scream it through the worlds of the living and the dead— This was not my choice!
"Yes."
"Excellent…" the Dark Lord said, his voice dropped to a hiss. That horrible snake was slithering around him excitedly.
My stomach was gone. My heart was in my throat. I couldn't think. I knew I was in too deep, but there was nothing I could do…I swear I didn't want any of this to happen.
Five words changed my life. Changed all our lives. Ended theirs.
"Where are they?"
"Godric's Hollow."
