Jann is minding his own business. He is playing by himself in the courtyard with a wooden sword: this definitely constitutes minding his own business. Nothing that follows is his fault.
Distinguished, sophisticated lack of purring matches it.
Eventually Jann hops off to go out in the garden and see if anything there tastes better than carrots and lettuce. He is extremely alarmed by the shadow of a hawk, goes back inside, investigates under all the furniture with enough room for a bunny under it, submits to being dusted by his mother, has lunch (broccoli and celery and an apple slice), and goes back to Milo's room to see how Milo is faring.
