Read some books on emotional intelligence, try to exercise your empathy and imagination and then go back and rewatch the episode. Or not, you can always stay blissfully ignorant.
Lisak No you didn't. The whole point of the episode is that even when you love your adoptive family you can't help thinking what it would have been like with your biological parents. All adoptive children go through this and they shouldn't be shamed for having feelings. And on top of this it's a transracial adoption.
