Since Cathy found out that Kinsey was her brother, she was no longer cold or wary when she met Kinsey. Cathy also confirmed this to her uncle. Her uncle showed her the lab test results and told her that she was indeed Chloeny Paxton's real daughter, while Daniel, who had been a father figure for her, was her mother's younger brother.
The name West was not Daniel's real surname but the surname of her adoptive mother. Cathy's three younger sisters were her cousins bear the family name Paxton. Meanwhile, Cathy... Benjamin didn't know who her birth father was, so he decided to use Paxton's name.
Cathy already knew what her father's name was and the surname that follows her. But Kinsey forbade her to tell anyone, including her uncle.
She didn't understand why she should hide her identity, but she just complied. After all, her uncle had also kept his identity hidden for years. So she did not feel guilty about having to hide the identity of her birth father.
