Oliver's Slytherin ((COMPLETED))

(((Not the 1st part))).

I just wanted to start this off by saying that some things won't be canon. I know that Oliver is older than Fred and George but for this story they're in the same year. I also want to add that Harry Potter and the rest of his year will only be 2 years younger in this story. This is just avoid confusion :). Also I know most people usually do get put into the same house as their family members, but you and your family don't. The tables won't be set out the same.
