His last encounter with the troll is in his thirties, married and with a child. He goes back to the town where he was born and moved into a house where the railway station used to stand though his job in London requires him to keep a flat there. Consequently, because of the distance and freedom that come with it, he ends up cheating on his wife, which in turn, causes his wife to leave him. Feeling dejected, he wanders off and finds himself on the bridge once again. Jack calls out to the troll, willingly giving himself to the troll to be eaten. .
These three separate events on the bridge states Jack's inevitable future. His future has already been sealed when he first encountered the troll. As if Jack's life was already obligated to him. When the railway tracks at the beginning of the story were being torn down, meaning London was the only way to go and that Jack's town was "the end of the line, " (1) a foreshadowing ensues. Jack ends up finding himself on the bridge on more than one occasion while growing up, thus implying that he was destined to see the troll, and be eaten by him. As for Jack's realization of himself, of how he had lived only for himself and his selfish intentions, it is inferred when he began to silently sob, after calling out to the troll and no one was responding, on his third unlikely appearance on the bridge. He was willing to give up Louise, in exchange for his own life despite being in love with her at that time saying, "Don't take me. I don't want to die. Take her. I bet she's much tastier than me. And she's two months older than I am. Why don't you take her?" He opened up to the idea that because he had a flat in London where he works, without his wife with him there, it meant that "it was fairly easy to get laid" if he wanted to, and which he did. Hence, he only sought for the pleasure of his own wants over the people he supposedly cares for.
On Jack's first two encounters with the troll, he constantly stated the things he has not done yet, things he has not learned, and places he wishes to go to.
