After
leaving Lily's Sorting, Sirius headed straight back to
James's...only to find the area deserted. This could only mean one thing: James had been Sorted. It was over. Time to settle in with Prongs.
The only question was, where did the Hat place James?
Sirius decided to assume that things had gone his way. He hurried down to the Slytherin dungeons, hoping like mad that he would find James sprawled on a sofa in the common room with a Firewhisky in his hand or swinging in the hammock in the Slythendor suite.
Unfortunately, there was no sign of James in the common room, and the suite Sirius shared with Harry, Ginny, and Ron was deserted. Sirius started to feel panicky. Maybe James had just wandered down to the kitchens to nick a bite to eat before bedtime. Sirius decided to look for him there...and in the Great Hall...and outside Ravenclaw Tower (maybe he wanted to have a drink at the bar before heading back to Slytherin for the night?)...and in the various boys' loos...and in unlocked, empty classrooms...until finally he had run out of places to look...except one.
Gryffindor Tower. Reluctantly, Sirius headed up to his old home. He hadn't been there since he had used the passwords Crookshanks had stolen to sneak in and attempt to kill Wormtail.
Please don't let James be there, please don't let James be there, he repeated over and over in his mind. Maybe he and James had just crossed paths elsewhere in the castle. Maybe James was waiting for him in Slytherin right now. Sirius would just quickly poke his head into Gryffindor, and of course James wouldn't be there, and he would go down to Slytherin to find James waiting for him after all. Yes, that's how it would be. But first he just had to quickly check in Gryffindor, just to prove that James wasn't there.
When he arrived at the Fat Lady's portrait, Sirius realised that, once again, he did not have the password.
Aaaand history repeats itself, he thought. He wasn't even going to try to reason with her; she probably hated him for ripping her canvas to shreds several years before.
Instead, Sirius slumped to the floor next to the portrait and waited for someone to arrive and let him in.
