"Hope you're telling the truth."
John said dejectedly, a long time after their conversation.
He found it hard to trust Americo, but deep down, he hoped that Americo was telling the truth.
John didn't want to meet Americo in person because he knew that it could end up in one of them dying.
He stopped asking questions and realized that even if he did ask, Americo wouldn't answer. If Americo wanted to tell him the answers, he would do so without being prompted.
Americo appeared calm as he spoke to John, "The answers to these questions are something you must seek out for yourself. It will require the strength you possess to find them."
There was a part of the truth that was too cruel to be revealed to John. It would deal a great blow to his psyche, and possibly render him unable to recover.
John was still too weak, but as he grew stronger, he would naturally understand all the truths.
