Hey guys....I don't know if you have heard this but i would like to share you guys this. After I solved the phone mystery by typing 62442 I got the paper of Harry Potter 1. I analyzed it and in it, it was written that Nicolas Flamel created the philosopher stone and he is 500 years old. The thing couldn't read/understand in that paper was is he alive or dead. If he is alive I have a feeling he is the half blood prince. If he is dead and he has a son, the son would be the half blood prince.
