Ali (the real Ali) kills Courtney.
Alison killed her twin sister Courtney. The only reason why she killed her is because she stole her perfect little life and alison is in a mental home and Courtney is dead
Alison kills Jenna, Ian, and her crazy sister, Courtney, she wants to frame Billy Ford, the gazebo worker for killing Jenna, and her sister who stole her life, Courtney. Ian she kills I believe just to kill him, but I'm not sure.
Ian kills Allison.
Alison doesnt get killed she has a twin sister named Courtney that is mental and Ali kills Courtney
I'm sorry if I don't answer this right, but in refferal to A, the reason alison does this is because she doesn't want the secret out. (She kills courtney earlier in the season) and courtney has told the liars all about her secret and practically destroys ali's life, getting revenge she kills courtney and then starts texting the liars but has a few minion-type high school kids helping her (mona&jenna). The overall reason is because she is afraid that if the liars tell something might happen.....
He lives to the end when Alison kills him
