Harry's shouts broke off, and he choked on a sob, his fists still clenched at his sides.
"I —," Hermione's lower lip trembled. "Harry,...I'm s-sorry." With tears brimming in her eyes, she scurried out of the room. But not before Ron could shoot her a scornful look.
Now alone in the Gryffindor common room with his friend, Ron opened his mouth to say something, but he couldn't think of any words that might help in this situation. With an expression of uncertainty on his face, he tentatively reached out a hand to place on Harry's shoulder. When he didn't get the negative reaction that he'd been half-expecting, he slowly (and even more tentatively) wrapped his friend in an embrace.
After just a moment, though, Harry pulled away, wiping at his eyes. For a minute, they just stood there, not saying anything. Then, "I'm going to go up to bed now." Harry's voice was hoarse from the shouting and crying. Still at a loss for words, Ron simply nodded and followed him up to their dormitory.
