Dissendium 2.0

WHO: Sirius Black & Mary Macdonald, with brief guest appearance by James Potter.
WHEN: September 1, 1976.
WHERE: The Hogwarts Express.
WHAT: I'd say Sirius is having a better year with girls than Regulus is but HAHAHAHAHA.

( There were pranks to pull. Slytherins to take down. Girls to snog. )

WHO: Sirius Black & surprise guest.
WHEN: The very early hours of this morning, August 20, 1976.
WHERE: 12 Grimmauld Place, and then...
WHAT: I woke up at 4 from the sleep of the passed-out-drunk, was about to go back to sleep at 7:20, when Sirius unceremoniously informed me it was time, now-or-never time. So. Now it is.

( Sirius had, of course, been meaning to leave for years. )

WHO: Sirius Black, Cici Jorkins, and Lucy Goyle.
WHEN: The Love-In.
WHERE: Party dungeon.
WHAT: Sirius tries to be intimidating while drunk; partially succeeds.

( I won’t tell, but someone will. So maybe you want to have a talk with that brother of yours. )

WHO: Regulus and Orion Black.
WHEN: Shortly after this; probably about April 17?
WHERE: 12 Grimmauld Place, Orion's study.
WHAT: Sirius has so many feels. :(

( A part of him didn't truly think Sirius would be upset that Regulus was choosing to confront his father over this - he even thought his brother might be a bit proud of the boldness of the move - but it was still a conversation he preferred to have without interruption. )

( Howler to Sirius Black, love Mummy )

WHO: Sirius Black, Jove Lufkin, Lucius's hair and cock I mean peacocks, Narcissa Malfoy, Walburga Black.
WHEN: End of December, shortly before this.
WHERE: The Malfoy Estate.
WHAT: ...good, clean fun?

( You look like you could use a drink or eleven. )

FORMAT: Log.
WHO: Sirius Black and Maeve Macmillan.
WHEN: September 1974.
WHERE: A Gryffindor party, followed by the deserted Gryffindor common room.
WHAT: The epic, romantic tale of how Sirius lost his virginity. Including abrupt tense switch partway through!

( She was probably a great deal more jaded than any fifteen-year-old had the right to be, but to be fair, Maeve wasn’t a typical fifteen-year-old. )

FORMAT: Log.
WHO: Sirius Black, Walburga Black, Pollux Black, with brief guest appearances by Orion, Regulus, and Kreacher.
WHEN: December 29, 1975, in the hours after Jove and Sirius wreak havoc on Cissy's party.
WHERE: 12 Grimmauld Place.
WHAT: Sirius spends some quality time with his family.

( Still, he refuses to regret this, as his brother is sent to bed. )
