It's not much later, in Isabella's room, that she asks:
"So... is Alex really a dom?"
"I like having a dom and want to keep her. That's not the potentially bad part of this deal."
"No, the bad part of this deal is if you like it so much that you actually harm yourself and risk your health because of it. Your life's worth more than your relationship."
"No, you're in a relationship now, if you still don't like your life very much that's still depression."
"I am happy about you not kneeling at people. I'm happy you don't feel the need to do it, I'm just not sure this was the very best way for that to happen."
"With you at least telling your dom about the things you don't want so that you're both getting as much out of it as you possibly can."
...snort. "I had not meant it that way, it was entirely unintentional."
And when Easter break rolls around Isabella brings her pet to the train station and they go to Phoenix.
