It’s not unusual for people to go missing in Rosewood, the fictional town on Pretty Little Liars. However, some of the characters have seemingly disappeared without any of the characters even noticing, or mentioning where they have gone.
The troubled younger brother of Aria Montgomery (Lucy Hale) was a major character in season two. He had issues with depression, violence, and was caught burglarizing the homes of Rosewood. The last time we seen Mike Montgomery (Cody Christian) was in Season 2 Episode 22, “Father Knows Best.” Since then he has not appeared in any scenes in the Montgomery house, or even been mentioned by any of the characters on the show.
We all remember Hanna’s boyfriend season one. He was quite a catch, and the apple of Hanna’s eye. After she totaled his car she even had to work at his father’s office to pay for the repairs, which is where she discovered Jenna and Toby (Keegan Allen) were seeing a therapist. Her relationship with Sean (Chuck Hittinger) was also the fuel behind her meeting Lucas Gottesman at an abstinence meeting. He never left Rosewood, but never appeared in another episode after Season 1 Episode 20, “Someone to Watch Over Me.”
Holden was also a pivotal member of Season 2 when Aria began pretending to date him so she could sneak off and see Ezra after her parents forbid them from carrying on their inappropriate relationship. Holden (Shane Coffey) had some drama of his own when it was revealed that he had a serious heart condition and was secretly involved in a dangerous form of martial arts fighting. In Season 3 his involvement on the show took a strange turn when Emily (Shay Mitchell) remembered he was with her the night that she was drugged and Ali’s grave was dug up. It was also revealed that he had a VIP stamp to Noel Kahn’s cabin around the time Maya was hiding there. However, after Season 3 Episode 6, “A Hot piece of ‘A,'” we never seen Holden again. The fans were left extremely confused regarding his involvement with the A-team and the grave robbery.
A huge deal was made about Kate Randall (Natalie Hall), Hanna’s new step-sister, and her arrival in Rosewood. At one point the liars even suspected her of being involved with the A-team. After it was revealed on Season 2 Episode 19, “The Naked Truth” that she had framed Hanna and made it appear she was texting naked photos, she never appeared in another episode.
Noel is probably the strangest character to have disappeared from the story-line, since he seems to have been involved in multiple plot-twists and revelations. Noel blackmailed Aria and Ezra, was very close to Ali before she disappeared, dated Mona while she was “A,” had Maya hiding in his cabin days before she was murdered, and was also with Emily the night she was drugged and Ali’s body was stolen from the cemetery. The last time we saw Noel was on the Halloween special “This is A Dark Ride,” where fans speculate he may have murdered Garrett Reynolds and attempted to push Aria off a moving train. There were way too many unanswered questions revolving around Noel to drop him from the show. Hopefully he will return in June on Season 4 and some of the viewers questions regarding his character will be answered.
