SOFIA: Three weeks ago I had a visit from my mother. She wanted to discuss her plan to have an affair with my brother. She also told me my father wanted to have an affair with me.
SEBASTIAN: Let's slow down for a moment. These are your biological parents, for both you and your brother?
SOFIA: Correct.
SEBASTIAN: And by affair, do you mean a sexual relationship?
SOFIA: Yes.
SEBASTIAN: How old are your parents?
SOFIA: They're both thirty-nine.
SEBASTIAN: And how old are you and your brother?
SOFIA: I'm twenty-one, he's twenty.
SEBASTIAN: Very good. When your mother discussed this with you, did you have any indication that this situation might occur?
SOFIA: No, not at all. I haven't experienced or seen any inappropriate sexual behavior from anybody in my family, not even remotely.
SEBASTIAN: How did you react when she told you?
SOFIA: I had so many questions. It was such a strange conversation. I just wanted to understand what was going on.
SEBASTIAN: And what did you learn?
SOFIA: First of all, you should know that at the same time my mother was talking to me, my father was talking to my brother, telling him the same things.
SEBASTIAN: Interesting. So they coordinated.
SOFIA: Yes.
SEBASTIAN: How long had they planned this?
SOFIA: I'm not sure. My mother admitted that they've had an interest in incest—an incest fetish, they called it—for quite a while, but only imaginary incest, shared between themselves, with no desire to act out these fantasies in real life.
SEBASTIAN: That's common enough. I assume they role-played their proclivities, and this kept them satisfied.
SOFIA: That's exactly what she said. But something changed, apparently, when my brother and I became adults. They started to see a new possibility. They debated the idea for a long time and ultimately decided to approach us with this proposition.
SEBASTIAN: Now normally, this kind of decision rests on an intuitive sense of what the reaction will be. Because otherwise, if they had no idea how you would react, the risk would be too great, the fallout could be catastrophic. So were they correct in thinking that you would not react negatively?
SOFIA: I suppose so. I was surprised, of course, and puzzled, and really, just curious about how this came about.
SEBASTIAN: Did it help that it was your mother talking to you and not your father?
SOFIA: Oh, definitely. It would have been too much coming from him.
SEBASTIAN: What did you say to your mother?
SOFIA: Like I said, I had so many questions. We talked for a long time. It was... interesting.
SEBASTIAN: Was it awkward?
SOFIA: It wasn't so bad. We talked about these relationships in a hypothetical sense, so it wasn't that stressful. I felt like my mother's relationship with my brother didn't really concern me, so I could look at that objectively. Talking about my father, that was a little uncomfortable. But eventually I felt like I understood the situation, and I told her I'd have to think about it. Which she was expecting, because she suggested a one month waiting period before discussing it again.
SEBASTIAN: So you haven't talked to her about it since that day.
SOFIA: I haven't had any communication with either my parents since then, as we agreed.
SEBASTIAN: When you told her that you'd think about it, what was your state of mind?
SOFIA: I was... a little perplexed. I truly had to take some time to think about it. I couldn't give my mother a definitive answer just then.
SEBASTIAN: You didn't automatically reject the proposition, so you must have had some level of interest. And you didn't immediately accept the proposition, so you must have had some doubts.
