Just a small minor suggestion : How about you make Oz stalk harry and hagrid while cloaked for some time ....and when they come out of Gringgotts , he can steal the pouch with the philosopher's stone inside !!!! He must make some things that hide this , however .... First , he must change his appearance through a ployjuice potion or aging potion or something , as someone (dumbledore , voldemort or snape) may chech hagrid's mind and find the thief who stole the stone has such a small body and may be a child .... Second , he must buy a precious gem to replace it with the stone , so no one even feels suspucious this isn't the real stone (the precious stone that he replaces the philosopher's stone with must have the same appearance , and maybe be a little magical so they don't check it) ... As for how to steal it ... just hide nearby and levitate it out of hagrid's pocket while hiding it , or maybe just summoning it since he knows the name and appearance of it .... Hagrid is a huge clumsy giant , hemay not dense it wqs gone from his pocket , and it woukd be replced by the fake soonenough he won't notice anything ... As for why steal it : 1) he needs a powerful artifact/catalyst to fuse both his wands together , and i want the new fused wand to be on ethe same level as the elder wand 2) it is gonna be destroyed anyways , so why waste it ???
