'Greta and Sal came to Mesa Flats years ago with two ambitions; to open a restaurant and a museum. These seemingly separate dreams met on the only available lot they could afford and became Sal's Bratwurst and Culture.'
Sal makes numerous appereances in Stephen's Story as Stephen's best friend, and also helps him. Greta does not make an appearance in the story, but is mentioned once by Sal and later becomes playable when the story is finished.
Altough Sal and Greta are supposed to be married, they are in fact not and they're only roommates.
