"Where did the two of them go?" Harry thought to himself.
He rounded the stone corner of just a usual Hogwarts corridor and there he saw them. All the thoughts he had about the on going battle were momentarily lost upon a glance at his friends' shining faces. Ron had a cheesy grin on his face and his eyes were on Hermione as she described the pair's journey into the Chamber of Secrets to acquire the Basilisk fangs.
Harry was smiling too as Hermione looked directly into his eyes, not Ron's. All her glances were for him. But soon she too became caught in the moment and in her euphoric decision gave Ron a kiss on the lips. Harry's smile faltered for a fraction, but when Hermione turned away half-ashamed and half-embarrassed, he went with the situation. Her eyes showed her uncertainty in what had just happened, and as she gave it a little more thought, she accepted the fact she had just kissed Ron. Hermione knew this is what was expected of her, but to her, it didn't feel right, however, she thought she could work with it.
Harry could discern Hermione's wavering judgment, and for some reason, this made him feel happy. He had had a minor crush on Hermione since their fifth year, but afraid of rejection, he decided it was best if they remained friends. Seeing her kiss his best mate had sparked sudden jealousy, which was subdued by her reaction to her spontaneous gesture.
Harry knew this new-found "relationship" his two friends had wouldn't last long, and he would make certain he was there when Hermione needed him the most, to pick up the pieces. In the meantime, he smiled.
"Oi, you lot are great and all, but c'mon. We've got a diadem to find."
