The Son of Her Mother's Killer

"She left you, Fred... She left on the day of your wedding. I can't understand how you can give up so much for her. You're even willing to let your kids have her surname... How can you be so sure of her? You know father only has you, right? "

When Talia got near the dinning room, Roderick's emotional voice was heard and Talia slowed down as she felt a tug in her heart. She felt hurt that her intentions with Arthur are questioned, but then on second thought, Roderick's care for Arthur is what was more obvious than his doubts over her intentions.

But what did he mean by saying his father only has him? 

"Don't bring up the past, Rod. I'm not giving up anything that-" Arthur paused noticing Talia entering the dining hall. Seeing Arthur with the bowl of soup, Talia felt her heart skip.

So they found out?
