PLL - dead, undead

So...
Am I the only one who keeps asking about if Ali is alive, who is dead????

I mean, I read the books and I know about the twin. But this was not mentioned in the series!!! And in all interviews no one ever asked and Marlene never said anything!!!
So really... I don't care about Ezra being A (well, of course I do...) but I really want to know who did they berried? Who A broke the teeth???

If I was one of the liars seeing Ali alive, my first reaction would be:
“who the hell did they find them? “

Does her mother know????
Her father? Her brother???
Really, I am going insane here!!!

Kisses,
A.
