Beth is an intellectual in a complicated relationship with nearly every member in her family. Especially her husband Jerry's. She is annoyed by his insecurities, and his cowardice. And along with her harsh, cynical demeanor, they have proven several times to be a terrible match. She is a logical person, but is ignorant of what isn't good for her and others. This is the case for not only her relationship with Jerry, but her father, and daughter as well.
Differences from in-show counterpart
The Beth of C-132 is less of a calculator and more of an adventurer. She still doubts, but not as seriously as she had in-series. She is also a bit tougher as well. Giving, and receiving lots of pain. Even murdering a patient of hers at one point, although hysterical in tears. This Beth also focuses less on her relationship with Jerry, learning to ignore him, and as a result, discovering more about herself. Something the in-series Beth has contemplated but has yet to like herself enough to do.
