I'm sorry, but I was looking through the Star Wars tag and I noticed that there were two of a quote for Slytherin. It was 'Do or do not. There is no try.' I don't know if this is relevant, just something I thought I'd point out
Ah! You noticed!
There are several (ten from each house) quotations that we redid after we switched to the new look, mainly because we were a bit worried that the transfer wasn’t going to be as smooth as it ended up being. We chose ten of our most favorites, especially from older posts, from each house.
