House Unity

In which Rose, Albus, and Scorpius are in Houses no one expected them to be, and of course Al thought it would be a good idea to promote House Unity to better the Wizarding world. Throw in some sort of "bug-bear hybrid creature" (coughBugbearcough) and, well, what else did you expect from places like Hogwarts and Hogsmeade? Scotland isn't very safe these days, I tell you. ONESHOT!
