Oh good, I must admit I was agonizing over the punishment part, because of that previous chapter, but I came to the realization that what Snape says in the heat of his temper will not always be what he does later on, especially after the terrible things Gavin had to endure at Draco's hand and also the kid was honestly sorry for what he'd done.  If he'd been a smartass or something, then I think Severus would've resorted to a spanking.  I have written a sequel, called Someone To warch Over Me, but can't post it here because it's a Gavin centered fic, and told mostly from his viewpoint, along with some of Severus's as well.  If you'd like to read it, let me know and I can email a copy to you.  Just post me an answer here.  I'm glad you liked the names of the twins, it took me a long time to come up with them, and my mom knows Margaret O'Brien.

Thanks for the great review and I've posted a short one-shot as well for the Winter Fest fic challenge if you want to read that too!
