Carol asks:
I agree (based on the same evidence) that Parseltongue is required to
open the entrance in the girls' restroom. My problem is with
Possessed!Ginny opening the Chamber using Parseltongue (which she must
have done, via Tom speaking through her). Wouldn't Myrtle have heard
the strange hissing and looked out to see what was happening? How
could she have missed seeing the basilisk come out? It happened at
least four times before Ginny herself was (somehow) taken into the
Chamber. Why wouldn't Myrtle hear and see what was happening? or did
possessed!Ginny choose times when Myrtle was absent from the restroom?
