Sirius watched Remus take care of the glasses. He had repaired them for Harry by now, of course. Also adjusted the actual glasses, because they were quite outdated. But now Harry could walk without stumbling, so he felt accomplished. "A scary story with a heroic puppy... Let's see what I can do."

He drew his wand and waved it, watching as a puppy appeared. And licked Harry's face, before running higher up. "There was a puppy, once upon a time. And the puppy had a really, really good friend, who was a wolf. They loved playing with each other."

There they were, tumbling around. All over each other happily. "But one day, the wolf got lost in the forest. That was very scary, because the forest was so big and dark and dangerous. Full of monsters." He did love to illustrate that.
