Not able to prevent himself anymore, Jack called out, "Mother…"
That's right! The person that Jack was hugging not long ago, and was looking at currently was none other than his mother, Anne!
This was the very person that about 6 years ago, he believed that she had died. He had attended her funeral, living all these years believing that she was dead. It was only during this year that suddenly, he felt that there was something that was not right.
In the end, he came to realize that what he had actually buried was just a clone. And the clone itself was just a body, and not one with life. And to say the truth, at that point, Jack felt devastated.
But of course, he also felt extremely happy. It was due to the fact that since he had buried a clone, that indicated that his mother might be alive.
