She's dead.
The real Alison never knew the girls.
Alison is the one who was not friends with the four girls, her mentally ill sister, Courtney, switched places with Alison and befriended the girls.
No they do not meet, but the girls think they met because of Alison's twin sister Courney. After Mona (A) died Alison became A, yet Alison never met the girls.
yes
Alison had a twin sister Courtney, and she was pretending to be Alison when they sent the real Ali away because they thought she was Courtney. Courtney was kinda rude to the 4 girls but Alison did not like the girls at all. Hope i answered your question :)
She plays tricks on them because they were mean to her when she wasn't popular
No the girls do not know.
Alison Stine has written: 'Wait' -- subject(s): Teenage girls, Poetry
The girls think this because he seems very suspicious and said that he doesn't remeber what happened that night. He also did not get along with Alison and knew that Alison was aware of his drug addiction.
Just like Mona, Alison gets a hold of Courtney's old diary and taunts the girls
Alison isn't dead, it was Courtney, Alisons twin sister. Alison never knew the four girls, it was Courtney pretending to be Alison, while her parents took the real Alison to a mental hospital. Alison killed Courtney, Jenna (apparently), and Ian. Then tried to to the four girls. :) SPOILER ALERT! :)
The girls are going to find out in episode 14 Donita's Answers
