In all honesty though, Harry and Hermione would not have lasted long enough to even think about defeating Voldemort without Ron Weasley there.
Like, Hermione would disappear in the library for whole days and Ron would probably go in search for her and all but drag her to dinner because “You have to eat ‘Mione. Don’t forget to eat.”
Ron spending his Winter Holidays with Harry instead of with his own family, because Harry needed him more.
Ron giving Hermione a Weasley sweater because It’s colder out here than I thought it would be and the twins would tease him, while he insisted it wasn’t like that.
And Harry was constantly getting in scuffles with the Slytherins, so Ron, who’s Mum taught all her children household spells, would fix Harry up in their dorm room, so ‘Mione wouldn’t see and get angry.
Hermione would catch the flu and Ron would take her to Madam Pomfrey, and lecture her gently on how if colds went untreated they could get worse, while Hermione rolls her eyes and she only has the sniffles Ron, it’s not the plague. Please find your chill.
When Harry would start to break, Ron would get him blankets and sit up by the fire all night, while Harry pretended nothing was wrong, despite the fact that he was literally always in mortal peril and his emotional state was always frayed.
I am a firm believer in the fact that Ron Weasley kept Harry Potter and Hermione Granger sane and fed and relatively healthy in those early years.
