Appearance and personality[]
Becky can be described as very beautiful, sarcastic, sensitive, practical, fit, and gets along with everyone in the house. She is known to have good judgment and being predictable (especially when the boys don't follow her advice, proving she was right in the first place). Becky is often seen giving advice and serving as a motherly figure to her four nieces and nephew. Whether it is about boys, love or growing up, Becky is always the first person to make sure her nieces and nephew are okay. Although she is not the greatest cook, Becky likes to help around the house and go horseback riding in her spare time.
