What will happen when Harry Potter is re-sorted into a different house. Will this cause emotions to run high or will it put him in more danger?

As if Harry's year wasn't bad enough already. Now he has to have a Potions tutor too? Why can't the universe be on his side for once? Oh yeah... he's Harry Potter. Set during 6th year. Warning(s): mild language and (Eventual) Draco/Harry and everything that Drarry entails! Not your ship? Get off and swim.
