Harry wasn't usually an emotional person, and now he was feeling all of them at once. Draco married a woman, but he didn't love her, he'd been in love with a man who didn't love him back. So he was gay. Harry couldn't help the little surge of excitement, even as he firmly squashed it down. This wasn't his Draco. They didn't have that shared life.
"Your Mum was so excited to be a grandmother," he said absently. Of course there hadn't been a baby, and now there never would be. But she'd been over the moon when he and Draco had told her. Things were still weird with Lucius, but Harry had gotten really fond of Narcissa Malfoy.
He took the icecream, still not wanting to look directly at Draco. It reminded him of Knickerbocker Glories. He'd never actually gotten to eat one of those.
