While the staff is working on her, someone mentions that "even her fiance didn't know about it" indicating she hadn't shared her suicide plans with anyone.

Six weeks after her recovery, Carol returns to work, where it becomes obvious that while she is still attracted to Doug, but she harbours some animosity towards him.

Carol tries to adopt an abandoned Russian girl named Tatiana, who has AIDS, but a background check that showed her attempted suicide only months earlier causes her application to be denied.

While caring for Tatiana it was revealed that Carol was half Russian and was able to speak the Russian language to a certain extent when she said that her mother was Ukranian and said that her mother tried to teach her Russian, but she didn't cooperate with it.
