At Cha Mansion
Karen was so pissed off that she wanted to add poison to the tea that she was about to serve on the veranda. She did not like how Kenzie was acting coy. She had to do something to destroy Kenzie's relationship with Daryl because that was the only effective way she could think of getting rid of Daryl.
Daryl was obviously in love with the woman. The newlywed couple was too obviously in love with each other and it did not bode well for her and Harry. Kenzie had a powerful background and Karen could sense the cunningness in her aura. So those two must be separated before Kenzie could further influence Daryl.
She composed herself, breathing loudly before she grabbed the tea tray and walked directly onto the veranda. She could have asked the maids but she needed to portray the perfect family image, so she decided to serve the tea herself instead.
