TONKS AND LUPIN ALMOST LIVED, BUT RON AND ARTHUR WEASLEY ALMOST DIED
Authors are allowed to change their minds but should probably think long and hard when it comes to matters of life and death! It seems inconceivable now, but Rowling admits that about halfway through the series, when she “wasn’t in a very happy place” in her own life, she considered going back on her previous commitment to herself to keep the Golden Trio alive, and almost killed off Ron Weasley. In retrospect, she now believes that she wouldn’t really have been able to do it, but at the time, she entertained the notion “out of sheer spite.”
Arthur Weasley’s near-death was a subject of more serious deliberation: Rowling felt uncomfortable with the idea that the entire Weasley clan should survive (since purely on a statistical basis, that would have been hugely unrealistic), and she thought Mr. Weasley might be the one to go. She decided to not go through with it when she realised how much of a blow such a loss would be to not only to Harry, in whose life Mr. Weasley played the most stable father figure, but to Ron.
Rowling decided she needed to keep Ron "intact" by sparing Mr. Weasley. The honour of being the Weasley to die in battle therefore fell to Fred: Of the two twins, Rowling had always written George as the more sensitive one, and Fred as “the funnier, but also the crueler of the two.” Hoping to circumvent fans’ expectations that George, the more passive of the pair, should be the obvious choice to die, Rowling decreed that Fred had to go.
Rowling never intended for Lupin or Tonks to die in battle. Although she wanted to spare Ron the loss of a father, she did later decide that she needed a character to lose both parents as a means of bringing the orphan story full circle. Teddy Lupin, like both Harry and Neville, grows up without a mother or father, instead entrusted to the care of relatives; yet Rowling intended to show that unlike the two other boys who grew up without a traditional nuclear family, Teddy was able to grow up with loving caregivers in a world that, after Voldemort’s fall, was “a better place.” She also emphasises that Teddy benefits from an even better godfather than Sirius: Harry becomes a true father figure to Lupin’s son, and despite his orphanhood, Teddy turns out okay.
