Because they befriended the fake ali and Ali would of nver been friends with the four of them.
No Jason is in love with aria not Spencer. Spencer and Jason are brother and sister which makes Spencer and Ali sisters.
Ali isn't dead. The whole time it was Courtney pretending to be Ali. Courtney is sick in the head and somehow managed to switch places with Ali, then Ali came back and killed Courtney :)
no , ali killed courtney who was pretending to be ali
spencer drives a Toyota highlander hybrid
SPOLIER Ali had a twin sister Courtney, who Ali's parents wanted to keep a sercet. Courtney always wanted Ali's life because she (Courtey) was mental ill. So when the PLL's (aria, hanna, Emily and Spencer) came over to steal the flag Courtney, became friends with them because she couldn't be friends with Naomi and Riley. Ali had to be Courtney, so she killed her the night Ali (Countney) went missing. The PLL's soon met Courtney (real ALi) who told them she was the real Ali and always their bestie. (Which was a lie) She took them to her summer home and tryed to kill them. They all wonder because Ali coudn't have left alive but they never found her body. She also killed Jenna and Ian, they knew about the switch. So we wonder Is she alive...
Ian grabbed her but she was dreaming
Ali was never friends with the pretty little lairs. It was her twin who was mental and loved to take over Ali's life. After Ali killed her twin (who everyone assumed was Ali) she went back to the mental institue. When Mona died, Ali found her twins journal that had all of the pll's secrets in it and used that to torture them. In the book Ali states she wouldnt be caught deade being friends with Aria,Emily,Spencer, and Hannah. So thats why she messed with them.
Ali/Courtney dies because the real Alison killed her for revenge of stealing her life, Mona Vanderwaal falls off a cliff as she was trying to kill Spencer, then Ian Thomas gets killed by real Ali because he knew too much, Toby committed suicide because Emily thought he was A and Toby thought she meant the time when he touched Jenna, A girl named Tabitha Clark (the liars thought she was Real Ali), Jenna gets killed by Alison because SHE knew too much.
Basically after Mona dies, the 4 friends think its over. But then all of a sudden they start receving weird texts again. Another shocker is that Ali's twins sister arrives in Rosewood. At the end it is known that it was Ali's sister (who became friends with the PLL ) who actally dies and the twin who arrived in rosewood is actually Ali. And basically A is ALI
Ali was mad that Courtney took her life and that the PLL were friends with her sister and not her. And, while she was at the mental hospital she became a little insane.
Mrs. Dilaurentis payed Cece to kill Wilden
no Mona is not dead Spencer found out that a was Mona so Mona tried to push her of a cliff but mona ends up falling and they think she dies but later we found out that she was put in a special hospital for crazy people hope that helped on the pll mystery
