"I haven't entirely ruled out changeling." It's almost a joke, but- Merlin, he has been something to deal with. Setting Integra's cup down for her (there's sugar, lemon, the rest- Narcissa doesn't presume), she says, "My Lucius has been out, I haven't had the opportunity to tell him yet. The other one is sleeping upstairs, presently. I thought I ought to have him where I can keep him on a short leash, at least for a bit."
