Okay, I LOVE bonding, and I love it when magic and sex go together in a mind-blowing kind of way, so this was really a pleasure to read. The description of the wedding was also very beautiful.
I could probably have used a bit more difficulty/angst, say on Janus' side, and I missed Ron's reaction (even though the one Hermionie predicted was spot-on) to the whole proceedings. But those are, of course, minor things. Overall, I'm all wrapped up in a happy blanket from this one!
