Val (on Earth, Valasca on her planet): an alien woman who has come to Earth to scout Earthlings. She is a psychologist / anthropologist and is smart, pretty, kind and inquisitive. She truly wants to figure out these earthlings. She believes they can be a great people.
Amber: another alien woman, she is a pure biologist and not as open to Earthlings as Val. She looks at them more as test subjects.
