Who else think A is a group of people?

i agree and disagree at the same time i agree because there's noway one person can check up on 4 girls all the time 4 girls who live in diffrent houses,each one has their own secret.unless A is supergir/boy/man/woman whatever

i disagreebecause even thought allison cased alot of trouble for many people y would they take out on her friedns they r as much as victim as they r

We think A is a group. We think the group is Mona, Lucas and Jenna beceause they all hate allison par the way Allison threated them.

Are toi a pretty little liar? I know I am!! I know some PLL secrets, now if toi do not like spoiler alerts than don't read it! Ok so, Alisoin has a twin sister her name is Courghtney. Courghtney had mental issues her mom was going to send her to a mental instusion, but she sent Alli instead. So Courghtney pretended to be Alli and became a populaire girl with the only other people she knew, Aria, Hannah, Spencer, and Emily. When Ali came back as Courghtney from the mental instution they were having a slumber party. Courghtney as Ali went out side to do something, i'm not sure what, but then Ali as courghtney killed her twin sister par pushing her into a hole. (Ali killed Courghtney) So Ali, she is still alive! toi know those times Emily, and also Spencer saw Ali in a so they thought a dream, but nope it was real life! Also in the Halloween episode one of the twins was telling a story about twins, and in the theme song "Two can keep a secret if one of them is dead." Now I am pretty sure that "A" is a group of people, defenitley Mona, probably Ali, now all of these are all maybes, Lucas, Jenna, Garrett, Jason, and someone very unexpected. Ali I think is the group leader of "A"!
