Tony's patronus doesn't take much longer to finish - hers is a gigantic eagle, nearly as big as Feral's thestral. (It can sit on Bella just as well as the elf owl can, since they're weightless.)

Bella makes no progress. New books on the Philosopher's Stone, received on her birthday, get mist just like the first one did, if a little more anemically. (The books are not as good as that first one.) Feral works on being an Animagus; he doesn't have it down before winter break, though. He also keeps telling Bella about what's been going in Herbology, although she has to translate his ramblings and half-formed written scrawls into usable notes by herself.

Bella does not get Feral a Christmas present, per request, but she gives Sherlock a book about prophecies and Tony a book about various failed attempts to integrate magic and technology. Euterpe can't carry them both at the same time and Bella wants her free for sending letters anyway, so she just brings them with her to hand over after winter break.
