I love and hate this episode at the same time. On the good side I love how such a magical place could exist, a place in which you can go and pick up people to replace those members of your family who might be not up to par with your expectations or what society calls "good". On the bad side I hate how the society in this episode has evolved into a no strings attached society, no burdens, (if you fail you are out). What happened to "i will be by your side in good and bad". Seems like the direction in which our society is moving.
The parents in this show realized too late that they were wrong and lost their only daughter. I wonder if they felt bad about it afterwards since they didn't care much for the girl, actually I think they were released from a load on their backs.
Hurt people hurting people.
