"I didn't know. I never knew Kaylee would get engaged to Mister Black." Kaylee did not know that her mother had planned the engagement behind her back. "Nor did I know that Kaylee will fall in love with that man." she never really knew that her heart would fall for Declan.
Everything Kaylee explained to Jacob was the truth and not a lie. But she said it by using the identity of Nicholas, who seemed to understand what Kaylee felt.
"When I heard that Kaylee was engaged last weekend, I was as shock as you are. As far as I know, she... she admitted she likes someone, but I'm sure that person was not Mister Black."
Kaylee felt sure she liked Jacob and felt more comfortable and excited about meeting this young man than Declan. But as time went by, she realized her heart and soul had fallen on Declan from the very beginning.
