Fanon:Sarah Beaker

Sarah Curious is the daughter of Nikto Curious and River Curious Remarkable is that while her father is an alien she didn't inheritate his green skin, what is kind unusual because the alien genes are normally dominant.

Before Birth
When River discovers that he is pregnant Nikto is shocked, he looks more like his alien father than he thought. River doesn't mind and loves the idea of something growing inside him. Nikto realises his life is looking much like his father's and his forever during engagement with Nervous Subject so he suggest that he and River should marry (or get a Joined Union) fast.

Babyhood
Sarah's baby years were peaceful, she was an easy baby and spend most of her time sleeping.
