Without Ron and Hermione (well, mostly Hermione, to be honest) Harry Potter would probably only be a third of the hero he is. The introduction of the ginger, freckled, jumper-hating Ron and the bushy haired, eternally clever Hermione would form a trio so foolhardy, hilarious and almighty, that even that pesky Lord Voldemort couldn’t touch them. (But more on him later.)
It’s bizarre to think that Hermione was, at one point, just the irritating know-it-all in their class. How little Ron Weasley knew when he made that ill-fated assumption. Seriously though, best best friends ever.
