Now that Cassidy appears to be more than willing to tell her story, Damien finds himself feeling more bewildered than ever.
He knew how much she insisted to keep her past as a secret. Before she lost her memories, she never told anyone about it. Her tenacity to never reveal it was like some precious keepsake she got from her deceased grandmother-in-law who also happened to be the one behind her arranged marriage with Adrian.
Certainly, there was a reason why Cassidy was hiding her background from everyone. But now, Damien is getting the feeling that this reason is something that she has forgotten.
Since she couldn't remember anything past the age of eighteen, it could mean that she found the reason not to tell anyone about her past only after she met her husband.
When her memories were stolen by that tragedy, a lid had been opened - one that had showed everyone her true character. It showed a personality that she kept hiding for five whole years.
