Jack Joyce 杰克·乔伊斯

Jack Joyce is the younger brother of William Joyce and the childhood friend of Paul Serene. During the events of October 2016, Jack returned to his hometown in Riverport at the behest of his friend, Paul, on the notion that Paul needed help with a "life changing" project. When he learns that Paul and his brother had created a time machine, Jack helps Paul activate the machine and unknowingly creates a fracture in time. When time begins to break down, Jack becomes the enemy and target of Monarch Solutions, headed by a viably aged Paul Serene. When it appears his brother is killed by Paul, Jack attempts to avenge William before he is approached by Beth Wilder, a Monarch employee invested in preventing the End of Time caused by the fracture.
