Sarah had one question for Edward: "On the Christmas when Aiden was at our home and you were against me dating him. It was because of the information Vasily gave you, right?"
Edward responded with a small nod and Aiden lowered his head in shame. Sarah's question reminded him that Edward knows about his past.
Sarah was focused on her father and she didn't notice Aiden's emotional struggle.
"Why didn't you tell me the truth?", Sarah asked Edward.
