While investigating the death of a young woman (Monica Barbaro) who enjoyed breaking into expensive houses to throw lavish parties when the owners were out of town the Stitchers crew is surprised by the arrival of Kirsten‘s (Emma Ishta) world-hopping boyfriend Liam (Jack Turner) whom she has never mentioned. A little more snooping into the home of the young woman’s latest victims uncovers an elicit affair, a blackmail plot, and the reason for her demise.
The red herring of Lesli Stone (Elizabeth McLaughlin) will keep the Liars busy for most of the episode, while allowing Hanna (Ashley Benson) to perform some grand theft auto and lead the girls to discover A‘s ability to track them (which their prolonged stay in the hospital didn’t reveal?), but by the end of “No Stone Unturned” the Liars‘ focus will return to finding Charles DiLaurentis who even his father has begun to suspect is still alive. Aria (Lucy Hale) is the only Liar directly targeted in the episode as she returns to the junkyard to find a new disturbing gift from their tormentor and struggles as her feelings for Ezra (Ian Harding) begin to resurface, but has she waited too long to act on them?
Buzzy’s (George Wendt) wedding to Tommy (Reginald VelJohnson) has everyone but Charmaine (Diona Reasonover) in a festive mood. Based on her own history with wedding fallout (which it takes far too long to take anyone to point out that it doesn’t apply AT ALL to the current situation involving a pair of older gay men that have no intention of having kids of their own) Charmaine momentarily talks Buzzy out of the wedding forcing Danni (Ashley Tisdale) to try and put things right.
Now an official team of three, Dutch (Hannah John-Kamen), John (Aaron Ashmore), and D’Avin (Luke Macfarlane) are hired to transport the surrogate mother of an unborn heir of one of the nine families that rule the galaxy (or something like that) in time for the baby to be born on his home soil and claim his birthright. Although there have been small stumbling blocks in the previous episodes, “Vessel” marks the first time the series gets into trouble for not spending more time world building and explaining the basics of this version of the future, the nine families, and the politics involved. The Nine have never been properly explained which leads to some confusion about surrogate cults, wealth, corporations, division of power, and rule of law that the episode skirts mostly around despite the fact that these issues have never been properly dealt with.
While Sam (Ben Bass) and Marlo (Rachael Ancheril) deal with a pregnancy scare at a routine doctor’s office visit Andy (Missy Peregrym), Juliet (Erin Karpluk), Nick (Peter Mooney), and Gail (Charlotte Sullivan) run into trouble when a routine prisoner transfer turns into a full scale prison riot separating the group from each other and any help from the outside. The episode jumps from the hospital to the various officers inside the prison and back to 15 Division as Traci (Enuka Okuma) begins an investigation into the connection between the two prisoners scheduled to be transferred and the a disgraced prison guard who knows far more about the situation that he’s revealed.
With the unexpected approval of his father, Hiccup (Jay Baruchel) and his friends embark past the known world of the Archipelago to find the unknown lands hinted at in the maps contained inside the Dragon Eye. The group’s first journey takes them to an island controlled by a Death Song whose mesmerizing call and fast-drying amber breath is the perfect method for luring in and capturing dragons just like the ones Hiccup and his friends have brought to the island.
While investigating the murder of a medical research assistant (Erinn Westbrook) who was working on system to bring back lost memories caused by traumatic events Kirsten (Emma Ishta) gets a small glimmer into the black hole of her childhood showing us why she’s such a natural at stiching by revealing her current job is far from the first time she has undergone the procedure. Those memories, along with a message hidden in the tape her legal guardian left her moves forward the mystery into the odd woman’s past leading to a key which may literally unlock secrets.
