Harry opened his mouth before anyone else could, determination overpowering his urge to cower. "It’s my fault, Professor. I was really missing home. And we have the most wonderful Observatory at home and Sirius would always take me to see his star this time of year, because we wouldn’t be seeing it until next year," Harry forced his voice to crack, which wasn’t terribly difficult considering how much he was trembling. "I was talking to Hermione about it in the library, and she was absolutely fascinated, but said she could never tell the constellations from the stars, so I offered to show her. She was missing home a little too, so I thought it might comfort her. Malfoy and Theo caught me sneaking out of the dorm, and followed me because I nearly fell out of the astronomy tower —again— a couple weeks ago. Neville must’ve seen Hermione sneaking out and gone to get her. Please don’t be mad, Professor. I was just missing home."
