Ron's anger had cooled drastically as he had roamed the hall, and he paused as he took in his brothers reactions.
"Well, I have to say that I got loads of looks, good and bad," and after a moment, he added, "I bet some of them would buy it, just for the effects."
He wasn't nearly as angry now, and there was a small sense of pride in his brothers for inventing something so ingenious, "I would rather have my tongue changing. So, how do we stop it? Do you have any idea how long its going to last?" and he suddenly looked worried, "Hermione! What do you think she is going to say? I'm supposed to give her flying lessons tomorrow!" he lamented, now worried she'd scold him severely for letting his brothers muck about with him.
