They weren't in a mental hospital. When Hannah was in the hospital, she had a dream and Allison was in it.
Hanna's and Alison's roommate in the mental hospital.
Alison is in the mental hospital because Courtney was in the mental hospital first but when she came back to visit she took all of Alison's clothes and bracelets and put them on and made Alison put on all of her clothes and they took Alison to the mental hospital.
Because she was mental
she sees 'alison'
Alison isn't dead. She had a twin sister named Courtney who had a mental issue. Courtney was always pretending to be alison. Courtney was pretending to be alison so they thought alison WA Courtney and sent her to a mental hospital. Courtney as alison then befriended aria Emily Spencer and hanna. The night that "alison" who was really Courtney dies alison was back from the hospital and killed her sister Courtney as revenge for pretending to be her. Alison then got shipped back to the mental hospital. Later when alison comes back again she tries to kill aria Spencer and Emily. There are two A's throughout the books the first is mona vanderwall who dies in the 4th book the second is the real alison.
Well in the book you find out that on the night she went missing, it wasn't actually Alison who was killed. You see, Alison had a twin, Courtney, who was a bit crazy in the head and before the girls became friends with Alison, Courtney pretended she WAS Alison so that she wouldn't have to go to the mental hospital. So then the real Alison had to go to the mental hospital and Courtney, 'as' Alison befriended Hanna, Spencer, Aria and Emily. Then that night 'Alison' (really Courtney) went missing it was the real Alison who killed Courtney, because she was mad with her. And the real Alison came over for the weekend back from the hospital and killed Courtney for pretending to be her.
Because she was mental.
