Can you obliviate a match that never happened (but a winner decided)? I assume so, but I want to make sure since it'll most likely happen after the round ends.
Also, what happens when someone sends two spells against you when you have protego. Both blocked? First one listed blocked? If someone else casts a spell towards the protego user but it has already been directed at someone else, does it block if it blocks more than two spells?
