Before I read the 6. Chapter

In my opinion, Alex will not be able to say anything at the beginning because he my might be very nervous , he had not seen his father for nearly 16 years. But I think that he will not be shy for a long time because that doesnt fit to his character. he could tell Tom about his feelings, that he was very dissapointed because Tom had naver tred to contact him even if he was in London. After thta he might tell him something about his hobbies and his life.
