This made me think of another question about Kreacher.  We know  
House Elves can apparate into Hogwarts (or at least within Hogwarts, 
Dobby may have come through the kitchens after traveling another way 
to the actual castle). We also know Kreacher is willing and capable 
of hurting another being (Buckbeak).  What is to stop Kreacher from 
going to Hogwarts and harming Harry if he were told to by Narcissa or 
Bella?

Just wondering.
