It is extremely unfortunate for Harry Potter that once the bond of an apprentice is made, it cannot be undone… that is until the Master relinquishes control. It is unfortunate for Mr. H.

They decide that this person should the Head of the House into which Harry is sorted, presumably Minerva McGonagall. But things, of course, don't turn out as planned, and Harry is harder to deal with than anyone expected. Nobody asked him if he wanted a mentor, after all...

The first time Severus Snape looked at Harry Potter, the newest member of Slytherin and The-Boy-Who-Lived, he saw James Potter. The second time he saw something different, something terrifying, and yet, something familiar.
