“Ginny showed up at mine this morning,” Ron comments, his eyes following Harry’s movements as he begins to wash the pan.
It takes a moment for the words to register in Harry’s mind; his stomach twists into knots, his mouth goes dry, and he can hear his heartbeat in his ears.
“Yeah?” Harry practically squeaks, even though he’s trying to seem nonchalant. He can imagine the look on Ron’s face, the look of a man who knows his best friend was once madly in love with his little sister.
