Hmm, it looks like Death Eaters are trying to fly toward the castle in that weird smoky form they like to take. However, a kind of magical force field repels them.
Well, that seals it: Hogwarts definitely is in danger from Death Eater types trying to break in.
Now we're following Draco (hmm, wonder what that transition means?), who's wandered to some random room in the castle where there's basically hoarder levels of junk. It looks like the Room of Requirement, which we've seen before in other HP installments.
In the room, Draco comes across a cabinet. Hey, it looks like the cabinet from that furniture shop…very suspicious.
