he must've known i'd run out on you. no. he must've known you'd always want to come back
Within the group, Rowling states Ron as the glue that keeps them together. He’s not the smartest or most skilled, but he’s the one with the most heart. When Hermione and Harry go off in their tangents, Ron’s the one that bucks up and keeps them grounded. He’s often the sensibility of the group without even meaning to be. As seen in Deathly Hallows when Harry begins thinking about Hallows, Ron is the one that can keep them moving when things get rough. He’s the chess master, the one that understands that some things need to be done rather they like it or not. Even though he’s often grumpy, it’s shown that his anger isn’t… quite as rash as Harry’s who lashes out without prompted reason. For Ron it’s always something building up or a protective nature. The trio have always defended each other, but when it comes down to it Ron’s the first one to be protective and will be the first to try and sacrifice himself for the others. As shown in third year when, on a broken leg no less, he stands and tries to protect Harry saying Sirius would have to kill them first, or during Deathly Hallows when he tells Bellatrix to take him instead of Hermione.
