What did the Pretty Little Liars do in Jamaica?

Answer 1

Spencer, Aria, Hanna, and Emily see a girl who looks like Ali but only has slightly different characteristics. The girl's name is Tabathia and she talks to each of the four girls individually hinting at some of the girl's past secrets that only Ali would know. Tabathia tells the girls by leaving a note under their room door to meet them at the Crow's Nest she has something to show them. Tabathia is acting weird and grabs Hanna by the wrist and looks like she is trying to hurt her. Aria pushes Tabathia and Tabathia falls off of the top of the Cliffs Resort. They see the body laying on the beach and run down there. By the time they run down to the beach the body is gone and no where to be found. The girls figured that the body was washed away into the sea and they here nothing else about it for over a year. They lose contact with each other andn never speak of what happened in Jamaica until they begin getting texts from A once again revealing their every move and secrets. A tells them to turn on the TV and in Jamaica Tabathia's body had washed up and they said it looks like she had been in the water for about a year. Tabathia's parents had been searching for her after she ran away. They identified her by screws in her ankle from an accident. Tabathia also had been in a fire at the age of thirteen so the four girls had killed an innocent person.

EDIT: The girl's name is "Tabitha," not "Tabathia."
