How do we know that she was deceased? Not all protraits show deceased people. Also, she might not have been Gryffindor.AB Ng 11:01, July 21, 2014 (UTC)
JKR said in this 2004 interview that all Portraits we have seen are of dead people. Which means that all Portraits we see in books 1 - 4 are of dead individuals.
It´s assumed that she is a Gryffindor because she guarded Gryffindor tower.
But I think she might might not attended Hogwarts, or another house. We cannot say that she went to Hogwarts or was in Gryffindor just because she guards the Gryffindor tower. portraits in bk 1-4 are dead individuals? Well, at least Lockhart isn't. AB Ng 13:29, July 21, 2014 (UTC)
