Who: James and Sirius What: reconnaissance for breaking into the Slytherin Academy Where: Forbidden Forest, school grounds When: Friday-Saturday, late night/early morning
The hotel room was dark. Normally, James would have been asleep at this hour, but instead he was awake, checking his watch regularly. Finally, as it drew closer to midnight, he slipped quietly out of bed. He avoided his instinct to kiss Lily's cheek, not wanting to wake her by touch. He had already taken his wand from its normal hiding place, and concealed it in his jacket as he left the hotel.
He found the darkest, most abandoned place possible, far enough away from the hotel that magic would not be easily traced back to where Lily slept, and Apparated. From his school days, he knew the castle grounds and the Forbidden Forest fairly well, and when he landed at the edge of the forest, it was dark but familiar.
He glanced around, but Sirius had not arrived, and no one else was to be seen. Risking another bit of magic - it felt rather nice to be using magic again, after so long passing as a Muggle - he transformed. As a stag, he concealed himself in the shadows beneath the trees and waited for his friend to arrive.
