From the time we knew that Sheila was back in town and Amber had moved over from B&B, I was hoping that the show would mention the connection.
Amber was introduced to us as Sheila's nanny (for daughter Mary, James is the father). Once Sheila was revealed to be the psychopath she is, Amber moved on the nanny for Brooke and eventually got involved sexually with and married Rick Forrester.
Considering her experience with Sheila, you wouldn't think she would jump into marriage with her new Aussie beau. However, she suspects the link to Jill Abbott and Kay Chancellor, and history has showed us she loves the rich boys.
