Samuel's reply matches Katrina's explanation perfectly.
That means that Katrina's visit that day was just a fluke. She was only there to deliver some documents to Carl.
Winnie continues to ask her son, "How many times has Katrina come to see your dad?"
Noticing the seriousness in his mother's tone, Samuel recalls carefully, "It seems that was the only time. What the hell is going on, mom?"
Hearing Samuel's answer, Winnie finally gives up on the idea. "Nothing. Bye," she replies before hanging up.
Winnie usually spends her time at home. Katrina rarely visits, and on the rare occasion she does, she is always with the whole family. There was no instance where Katrina had been alone with Carl.
Samuel is at the company for work every day. Since Katrina only went to see Carl once, there's probably nothing strange between them.
But why would Carl give Katrina 10 percent of his property?
The thought doesn't put Winnie's worries at ease.
