It's not much later, in Isabella's room, that she asks:
"So... is Alex really a dom?"
"I'm used to people assuming I'm a sub," shrugs Renée. "I all but encourage it at work. But - yes."
"I'm not sure how much brainpower I should devote to trying to figure out what to do in case he actually just pulls me out of school. I might just shapeshift and run away."
"But then I wouldn't have the nurturing environment of Selene and, again, wouldn't have you."
"Unless I somehow make a new identity for my new shape and enrol again..."
"I have no idea," he shrugs. "If I made myself younger and said I took a particularly long time to get out of the wilderness and that my parents are dead and that I don't have a birth certificate and I have a really common name...?"
"...yeah I think that's about as much brainpower as I'm going to devote to this before knowing more about how Tobias will react."
"How about we move the conversation back to the part where I get to know my dom's mom and we pretend the thing didn't happen?"
"Oh, of course," says Renée, and between bites of leftover pizza and the last of the tuna salad she talks about her current hobbies and her job and her friends and asks Sadde carefully-delinated similar questions about school and interests and his library job.
And he answers those and asks a few other relevant or clarifying questions back and tries to be generally charming and friendly and it's really really obvious he really really likes Isabella and other than Tobias his life is turning out much okayer than he'd ever expected it to.
And she lets the kids decide among themselves who's taking the couch and who's taking the top bunk in the twins' room.
Sadde's perfectly fine taking the couch, he's spent years in the wilderness, he's not picky.
