Ron followed Harry onto the lift, and nodded, "Good. I don't think it would be the same if I didn't have at least one of my friends there. Hermione's not coming. We decided it would be too strange."
Ron looked at Harry, wondering if he knew just how close he and the girl were. Ron thought Harry would suspect, but he wasn't sure if he realized how in love they were, and how close he'd been to asking her to marry him before all of this mess happened. Ron put his arm around Harry's shoulder, in a slightly comforting gesture, "I'm holding up," he said trying to keep up a chipper tone, "I've met her. She's pretty cute. Interesting. A bit different, but I like her. I think we can make a go of it. We have to, don't we? I'm just crap at getting to know women, is all."
He waited until the lift was empty to go on, "I was going to ask Hermione to marry me, Harry. But I waited too long. It's the worst but she went through with it, and I will to. We'll manage, somehow. We will," and he looked at Harry in the eye, knowing he'd never be able to tell Harry what he and Hermione had done. He wouldn't do that to his friend, put him in the middle of their secret.
