Eve

Eve is a third generation synth living in the Institute in 2287.

Background
She's a subject of a social experiment performed by Dr. Alan Binet, who wants to see if a synth can integrate into a human family. As such, Eve acts like a sort of surrogate mother to Alan's son, Liam Binet, although she's aware that she can never replace his biological mother.

Appearances
Eve appears only in Fallout 4.

Behind the scenes
Eve is most likely a reference to Eve of the Garden of Eden.
