A/N- Mrs. Weasley IS aware that Ron and Hermione are already a couple, in case that wasn't made clear.
Disclaimer- I'm not JK Rowling, blah blah blah, I don't own these people, or the Harry Potter books, as I'm sure you brilliant people have already figured out.
"Oh, Arthur, the plants outside need watering. I'll be right back," Mrs. Weasley said, jumping out of her seat and grabbing a watering can.
She relished in the perfection of the day; it was sunny and warm, reminding her of her young days at Hogwarts, most involving long walks on the grounds with Arthur. She walked around the corner of the house, smiling, and leaned down to water the newly sprouting daffodils, when she saw something out of the corner of her eye. Spinning around in surprise, she looked closer, and saw Ron and Hermione kissing by the side wall of the Burrow. Springing to her feet, Molly turned and opened her mouth to scold her youngest son; the words sprang to her mouth easily. Maybe a bit too easily, she thought, her face softening. They're 18. They aren't children anymore. Really, she discerned, she had nothing to disapprove of. This was Hermione- not some silly girl he met at Hogwarts, but his best friend for nearly eight years. And Molly Weasley had been noticing more between the pair of them, these past few days. She saw in Hermione's eyes a sparkle whenever she looked at Ron that was otherwise absent. And as they broke apart, Hermione looked nothing short of euphoric. To the unobservant eye, she would appear perfectly neutral, but Molly Weasley saw otherwise. She saw the small smile playing at her lips threatening to take over her face any second, her eyes shining brightly as she looked up at Ron. As they began to talk quietly, each smiling to themselves, Mrs. Weasley gazed at her son, wondering when he had turned into this new man. Hermione smiled up at him, and buried her face in his shirt. Ron said something to her and she laughed.
"Too bad it took us 'til the middle of a raging battle to realize that this would work out," Ron said, grinning. Hermione lifted her head and looked at him.
"I don't know, not really," she replied. Ron looked quite hurt.
"And what is that supposed to mean?" he demanded, stepping away from her. Mrs. Weasley restrained from walking over to her son and whacking him over the head with her watering can; Hermione obviously didn't mean that the way it sounded, and he should know that. Couldn't he see the radiance emitting from Hermione's face? Well, she reasoned, maybe not. Ron had never been as confident as he should have been, always putting himself down. Hermione seemed to feel the same way as Mrs. Weasley; she sighed exasperatedly, but her face softened.
"Don't be a prat, Ron, you know I don't regret getting together with you. Not in the slightest! All I meant, was that it didn't really take us until the middle of the battle to realize; things had been different between us for a while." She smiled. "Like at Bill and Fleur's wedding, you were jealous of Victor-" Ron's face hardened at this, but Hermione ignored him and breezed on. "You were jealous of Victor, and you asked me to dance. You certainly wouldn't have done that a few years earlier. Later, in Grimmauld Place, when your dad sent the patronus, you definitely acted differently than you used to, hugging me and such when I tried to reassure you. And when you got back to the Burrow on the night we all took Polyjuice to look like Harry, you must have noticed how I reacted when you got back..."
Ron smiled slightly. "Yeah, well..."
"And anyway," Hermione continued. "I think that we all sort of needed a... break during the battle. Something to... cheer us up a bit. Maybe it was for the best." Hermione's face flushed, and she stared down at her feet. The tips of Ron's ears turned bright red, but Mrs. Weasley noticed that he was looking noticeably happier now.
"Come on, Ron, it's getting pretty hot out here, let's go inside." she slipped her hand into his, and squeezed it gently. "You're a complete idiot, you know that?" she asked him, looking into his eyes. Ron grinned sheepishly.
"Yeah, I guess. But you're the one stupid enough to fancy me, so you shouldn't be talking." Although he said this with a grin on his face, Mrs. Weasley felt her heart breaking with the seriousness so horribly concealed in his voice. Apparently, Hermione sensed it too.
"Ron Weasley," she said, placing her hands on his shoulders and looking him straight in the eye. "That may just be the most foolish thing you've said to me in seven years." Ron raised an eyebrow.
"Oh?"
"Why wouldn't I fancy you?"
Ron mumbled something incoherent, staring down at his shoes.
"Ron, the one thing you've done over all these years that's made me the most upset- and that's saying something, considering all of the things you've done- is when you got together with Lavender Brown. Seriously. After all that you've done, that's what hurt me the most." Ron looked up from the ground, clearly struggling to do so.
"Really?"
"Really."
Mrs. Weasley felt her eyes stinging with tears; Ron could not have found a better woman for him, and from the sounds of it, Hermione could not have found a better man. Although at the time, the two were nothing more than a close couple, Mrs. Weasley may well have been the first to consider the true extent of what their relationship could become. And she was right.
