I swear, that woman acts as though we're married.— Professor Scara regarding Doctor Duff

Professor[1] Scara is a scientist found in the Science! Center in Diamond City alongside Dr. Duff in 2287.


Scara came to Diamond City and settled in with Dr. Duff because of the access to the laboratory equipment she provided.[2] In contrast to Duff, who is more interested in fun experiments and teaching biology lessons, Scara is a much more serious scientist, refusing to deal with visitors and referring them to Duff instead.[3] Though Scara mostly writes and speaks about her in frustration, Duff's dialogue script notes state that she is in a romantic relationship with her,[4] and that they are an odd couple.[5]

Scara possesses a great deal of knowledge about robotics,[6] and in addition to attempting to fix Takahashi's Japanese language subroutines,[7] she frequently goes on field expeditions for a couple of days.[8]
