"Dear Son…" The first words of the letter resonate in Lucien's mind. "I missed you so much…"
Despite all the curiosity and doubt, the most enduring feeling Lucien has about his mother is that torturous sensation of missing her; the thought that she might feel the same is deeply moving to him.
He can't help but read those words a few times, imagining how they would sound in his mother's voice before proceeding to the next part.
"I know you have many questions, doubts, and even resentment towards me, and I want to say that I am sorry for making you feel this way, but everything I did was for a reason…"
Lucien wants to continue reading the letter without jumping to conclusions, but he can't help feeling optimistic about his mother's feelings.
And he continues reading the words in the letter.
