I am so glad to see another chapter of this fic. You've done such a lovely job of showing their healing, both physical and emotional, and this chapter was great.
And about the following:
"You're more than welcome to stay, at least until Teddy is old enough to need his own room."
Well, that won't be an issue, will it? Because by then Remus will be sharing Severus' room... *grin*
