Jessica DiLaurentis (Andrea Parker) has the secret twin, as revealed in Tuesday's Pretty Little Liars finale.

Let's review: Jessica's twin sister, Mary Drake, is Charles/Charlotte's (Vanessa Ray) birth mother. Jessica and Alison's father (Jim Abele) adopted Charles while Mary was a patient in Radley Sanitarium. Mary, obviously free from her confines, is determined to get revenge for the murder of her daughter. That quest will be the most devastating for Alison (Sasha Pieterse), who just committed herself to the psych ward due to her long-lost aunt and new husband teaming up to make her think she was having delusions about dead mother.

The sour cherry on top of this messed-up sundae is, of course, Dr. Rollins (Huw Collins). He's been the one wearing creepy skin masks because he was actually in love with Charlotte, not Alison, and he's teamed up with Mary to torture those they think are responsible for Charlotte's death.

To say this is a tough break for Alison is an understatement. Rollins was the first person Alison had been able to sustain a romantic connection with since she disappeared from Rosewood before her sophomore year of high school. It seemed like Alison married Rollins quickly; but, from her perspective it felt like she had finally found someone whom she could trust and who understood her complicated family situation. He was someone that could sympathize with her loss of Charlotte and help her move on.

The betrayal of Alison is made worse by the fact that three of the show's other major couples had found time to reconnect during the finale. Aria (Lucy Hale) and Ezra (Ian Harding) had romantic reunion sex in his new loft after a heartfelt talk about his allegedly dead girlfriend. Spencer (Troian Bellisario) and Toby (Keegan Allen) were as thick as thieves as they looked into what Sarah Harvey (Dre Davis) is hiding at the hotel. Even Hanna (Ashley Benson) and Caleb (Tyler Blackburn) shared a forbidden kiss at the Lost Woods Resort (but that's not going to go down well for either of their significant others next season).

Pretty Little Liars: Are Aria and Ezra really over?

It feels more than unfair that the show's major 'ships all at least turned back towards each other, while Alison finds out that her person is actually a psychopath. Alison may have been the Queen Bee from hell in her teenage years, but she's turned into a compassionate, caring person in her 20s. She's now a committed, church-going teacher in a small town, and she's made penance for her teenage sins.

The next season of Pretty Little Liars still has a lot to unravel. If Mary Drake and Dr. Rollins are the ones torturing the girls, then Charlotte's murderer is still at large. Now the group will have to figure out who has kidnapped Hanna as well — is it the killer or someone else entirely? Our hope is that, among all of the upcoming reveals, they'll find time to give Alison the happy ending she's earned more than anyone.
