Of course, I know He was in Slytherin, Finnigan! That's what I was asking - whether Ravenclaw Corner was ever possibly Slytherin Corner, you know?

Because it's the very best spot in the library, so I'm sure when He was here He would have wanted the best. So it's possible, if Ravenclaw Corner hasn't been in that very spot forever and always, that at one time there were Slytherins who used it. And maybe the Lord Protector was one of them!

(It was certainly never Hufflepuff Corner or Gryffindor Corner, but Slytherin Corner? Maybe!)
