Do you know about Mrs. DiLaurentis?
I know she was murdered.
And I thought Shana did it,
but the timing doesn't really work out.
I had everything backwards.
But once I knew that Shana was following you
and then I saw her in New York
dressed like that, well, I knew she was 'A' then.
Have you heard from her at all since you've been back?
You have to be careful then,
because she's clearly still out there.
Yeah, well, there's cops at Rosewood High and all over town,
in case Ali's kidnapper comes back.
You need to be careful.
All of you.
I better go.
That's a new lock.
Let me get that for you.
