List of Pretty Little Liars: Perspective episodes

The first season of Pretty Little Liars: MonA, based on the books of the same name by Sara Shepard, premiered on March 6, 2018 and concluded on June 12, 2018. On April 13, 2018, ETV renewed the series for a second season consisting of 13 episodes.


Five years have passed since Aria Montgomery, Alison DiLaurentis, Emily Fields, Hanna Marin and Spencer Hastings find out the identity of A.D. (Hastings' evil twin sister Alex Drake). Five years ago, Mona Vanderwaal told the Liars that she called the police who "arrested" Alex and Mary Drake, but unbeknownst to them it was Mona's French boyfriend Mikel Gifford; they then moved to France with a dollhouse with the two trapped. Now, Mona and Mikel return to Ravenswood where they lay low as Mona calls in an investigator for updated information about the Five Liars. She then starts texting them, killing, taunting, leaking with the help of Mikel and other minions. In the end, the Liars find out that Mona is New A in a dramatic fashion leading to her arrest. Mona, who was informed by a minion of the Liars revelation, initiated her final plan freeing Alex and Mary Drake. Mona then goes to a central place in town where she is spotted by the cops as she is arrested.

Pretty Little Liars creator and showrunner I.

James C. Bristow, who portrayed a "police officer" in the series finale of Pretty Little Liars, was announced as being upgraded to a series regular for the Pretty Little Liars: MonA continuation.[79][80][81] All actors from the seventh season of Pretty Little Liars signed on to continue as a series regular, except Laura Leighton and Andrea Parker.[82][83][84][85][86][87] New showrunner Joseph Dougherty promised that the two would appear despite not signing on as a regular.[88][89] The two were later confirmed to appear in a guest role.[90][91] Julian Morris, who portrayed Wren Kingston in the finale, could not appear due to scheduling conflicts.[92]
