By now, Lillian probably has an idea on why Lewis decided to hide his identity back then.
It's as clear as day that this household is strict. Just from the looks of their body languages alone, she can tell that there's a thick barrier in between that's most probably made by their impenetrable fronts.
Even Lewis himself doesn't appear as loose as earlier, though he still has his usual cool. He seems to be on guard - almost as if he's bracing himself for an unprecedented turn.
His father, on the other hand, just keeps his silence the entire time. With how he is sitting in front of them with an enigmatic mien and inscrutable expression, he's practically towering over her like a dense fortress.
"Father, may I ask where Mother is?" Lewis finally started after a moment of silence.
"She said she won't come. You already know why," his father simply answered without looking, making him look at him in confusion.
