Why is it a concert violinist? Is that supposed to make this person like, much much more important than anyone else? Or can the violinist play soothing music during the nine months? Just seemed like a weird choice.
Also, if I were the violinist, I'd be really really pissed at the person who kidnapped me and put me in this position. Whereas I think a child of rape is probably grateful for having been made in the first place, even under horrible circumstances. That's where the analogy doesn't hold up.
