Upon Moss's debut, the character's age is revised to 17 placing his birth in 1995. Moss's JJ was described as Jack and Jennifer's "troubled teenage son," who returns from boarding school in London with a chip on his shoulder. CBS Soaps In Depth hinted that JJ would be in very heavy story. According to Moss, JJ is acting out because he is "in a state of confusion." Moss also explained that JJ's actions are because he is "still troubled by his father's death." Moss described the character as "very loving" and also "heartbroken." Upon his re-introduction, JJ is "all over the place and doesn't really know who he is yet." Moss revealed to Soap Opera Digest that JJ is going through the process of "becoming a man." In the midst of JJ's scheming, the series introduced Kevin Riggin as JJ's partner in crime Rory. The two begin selling drugs to make quick cash. JJ falls in with the wrong crowd because he longs to feel a connection. However, JJ does not have to worry about forming a "real bond", Moss told Soap Opera Digest. Abigail is immediately concerned but JJ resents his sister and mother as "he doesn't feel they grieved his father's death." JJ's anger reaches a climax when he gets into an altercation with Daniel but according to Moss, JJ had been looking for a fight. Soaps In Depth referred to Moss's character as "Hurricane JJ!" His return home isn't what he expected and he is uncomfortable that his mother has moved on. JJ feels that his family has "forgotten" about Jack. Though Jack wasn't always physically present, JJ felt a "sense of security" knowing his father was at least out there somewhere. When he finally does come, JJ does not feel that anymore. JJ definitely wants his mother to find happiness again but he feels it is too soon. Of the circumstances surrounding JJ's return, Moss hinted that there is more to JJ's story. According to Moss, JJ is at a point in his life where he is still a good kid, who is making bad choices. Storylines

Michael Fairman described the character's return as "long-awaited" and said Moss would "add to the young hunk quotient in Salem!" Jillian Bowe immediately hoped that Moss's JJ would cause trouble for Jennifer and Daniel. Moss was voted as the #1 soap newcomer in the June 10, 2013 issue of Soap Opera Digest with 34% of votes. Jamey Giddens praised Moss and claimed him as a "breakout, young adult star." According to Giddens, JJ becomes a voice for the fans of Jack and Jennifer who were upset about the Daniel/Jennifer (Dannifer) pairing. "I absolutely love it when he gives Jennifer and Abigail grief for being able to so readily replace Jack with Daniel," remarked Giddens. Giddens hoped JJ would cause even more trouble by "hooking up" with Jennifer's rival, and Daniel's ex-wife, Chloe Lane (Nadia Bjorlin). Laurisa Mahlin of Soap Central praised the dynamic in contrast to the usual romantic triangle for Dannifer. Mahlin explained that even though JJ is acting horribly, it was enough for most fans that he caused trouble for the hated pairing. Jamey Giddens later said that Moss's JJ was the "best foil ever" for the couple and that JJ gave the pairing a rooting factor. References
