If things were bad before, they took a turn for worse after that fateful dinner. Hermione avoided both him and Draco like the plague, isolating herself completely in her dormitory, and Harry had no idea what to do. He’d argued with Ron before, many times, in fact, but Hermione—they always stood together, unshaken, Harry and Hermione, Hermione and Harry. She helped him before the war, during the war, after the war, asking for nothing in exchange. Her only request was the Hex-Vow they made to each other after their respective break-ups and he could have said no at the time. He didn’t. He went through with this, barely able to function after Ginny left.
