80. If Hagrid had disobeyed Dumbledore and given Harry to Sirius on the night Lily and James died, Sirius would have been proven innocent, the Ministry would have found and arrested Peter Pettigrew and Voldemort would have never risen again. Dumbledore would have sent the Ministry after him, he would have been discovered in Albania and thrown into Azkaban. Harry and Dumbledore would have destroyed all the Horcruxes together in their own time, and all would be well. However - Harry would have never met Ron and Hermione on the Hogwarts Express as he did not need help getting through the barrier thanks to Sirius. They would have never said as much as a 'hello' to eachother. So maybe things do happen for a reason, even if it doesn't seem like it at first.
This is a load of bull. Sirius would have been assumed to have kidnapped Harry. And how the hell did we assume that Harry wouldn’t be friends with Ron and Hermione? They’re all in the same year in Gryffindor. This is a school for wizards and witches, there aren’t thousands of kids in a year especially if it’s divided up by group.
