"We've both been there with her since she was born or not long after. Tefe isn't really human but she decided that she wanted to be...or at least to understand what it was like so she wouldn't hate humans anymore." She didn't really want to change what she was she just wanted to not be programmed to hate people like she had been since she was a child, Octavia and Aurie had been her connection to learn about love.
