Shooting Hermione a bit of a sheepish look, Ron shuffled forward a bit awkwardly before falling to a halt a few feet short of her. Hands finding his pockets, he found himself unable to do no more than stare at her quietly for a few passing moments. She looked a bit older than he could remember, but it wasn't to the extent in which Ron found her completely unrecognizable. She was still Hermione; still the girl that he had grown up with. The only unnerving bit outside of the slight physical changes was that she knew things that he did not. It was a bit different when there were people spitting facts out about his life that he wasn't terribly aware of - they were the sort who read the books and saw the movies and Merlin knew what else - but with people like Hermione, Rose, and James it struck Ron a bit more differently when they suggested that they knew things of his future that he did not. It made him feel at a disadvantage. Even though he did have a bit more of an advantage over Hermione here, what with him knowing more about this world than she did.
Once he got his bearings, Ron flashed Hermione a weak smile. "I see you didn't have any trouble learning how to use the computer." Not that she would have. It was different with her, being Muggleborn and all.
