Debate 3 - Will we ever see Sirius again?

Lupin said he is dead, Dumbledore said he is dead. I think they knows whats behind the veil (I still find it weird to say that because it you can look at it from back and front. O.O) more than we do. JKR had a reason she killed off Sirius. We will know why in the last two books.

Dumbledore called that room the "DEATH CHAMBER", maybe that arch is a door into the world of the dead

It might be that once someone is threw, they can't ever come back, making them dead

There is already a forum for this subject 🙄
