Because she was usually in a mental hospital.
Courtney Alisons twin sister
In the show they say nothing about Courtney but in the series they are identical twins.
Yes
If you are referring to Courtney from the Pretty Little Liars book series by Sara Shepard, it is unknown if it will be on the series. What I do happen to know is that we will find out who "-A" is at the end of Season 2. I found this out on the website, abcfamily.com and go to the Pretty Little Liars blog. As you know, Courtney was in the books, and honestly I hope she's on tv. That would be a great twist. Hope this helps a little, considering it's the best to anyone's knowledge at the moment.
She doesnt but if she did it would be to throw the pretty little liars off.
In the books, Jason DiLaurentis does know. He is closest to Courtney out of the twins
She stole Ali's (Courtney's) diary.
In "Pretty Little Liars," it is ultimately revealed that Courtney DiLaurentis, Alison's twin sister, is the one who dies. Throughout the series, Alison is believed to be dead, but it is later uncovered that she had been alive and in hiding. The confusion arises from the twins' identities and the manipulations surrounding them, but Alison does survive the series, while Courtney's fate is sealed.
Jenna knew the entire time that Ali had a twin named Courtney
