Well I think that we have a good reason to talk about it... JKRowling wouldn't give it to
Harry Only to say he could have avoided
Sirius' death... I think there's much more.... it can be either a way to contact
Sirius, a key to other mysteries or something that can help with the horcruxes...
It is said that mirrors are strongly connected to the souls so It could be a way of destroying the horcruxes without being hurt as it happened to
Dumbledore, maybe placing the Horcruxes between the two mirrors... or it could be a way to stuck
Voldemort and Destroying him... cuz his soul has been too ripped...sorry about my mad theories...
