As for Luna I wanted to play matchmaker a bit with her and Ginny but it seems like I didn't need to. One of the times I was doing prefect rounds I found them pawing at each other in a broom cupboard sucking on each others face. While I'm certain I've been in a similar position with Harry, I'd never had the chance to see it from an outside perspective. We all had a chuckle about it later and with a couple of rounds of teasing it was left alone.
