In Harry's 3rd yr., Halloween night, Sirius sneaks in to finish Peter Pettigrew. A twist: Sirius's life depends on a man who's hated him for years (p.s., its not snape!) doesn't diviate from JKR's version, but tells a v. different story. *Complete*
Sirius, Remus, and Peter are babysitting little Harry, and Sirius takes a quiet minute to consider Remus. Is he a traitor? Very sad. Sirius POV, not slash.
