How can you people not believe this was planned from season 3 on??
They decided who A was after 3x02 was done. And then in 3x07 CeCe appeared for the first time. Marlene said they wrote her in knowing she's A. The timing matches perfectly.
When she comes to the show she already knows about stuff that happened AFTER Ali disappeared. She is the one telling about Paige-Alison violent past and then at the exact same time 'A' sets Paige up for being 'A'.
In 3B it's said "CeCe Drake, back from the dead"... meaning she was locked up to Radley and had to disappear due to it. We see her in the rush packing her stuff and moving out the episode AFTER the elevator accident. In season 6 we learn around that time Mrs. D was hiding somebody in the Caorl's house. Again the timeline matches. BTW Jason was in the elevator accident RIGHT after showing Emily that CeCe was with Ali and Mel and Wilden in Cape May
Now season 4 was called The Season of Answers. And not for no reason, they revealed Big A's identity, Alison being alive and Ezra being shady. The entire 4A led up to CeCe being the main suspect, she was even wanted by police for killing Wilden. You can see her in the hoodie in 4x11. Oh and notice how she was in Ezra's lair and 2 episodes later 'A' appeared wearing the EXACT same costume that Ezra.
The entire 4B was a huge game for CeCe. 'A' did everything to make Ezra look like A. She stole the diary, changed the text and put it to Ezra's desk for the girls to find. The only person who knew about Ezra's book, diary, costumes etc was CECE DRAKE.
In season 4 finale "A is for Answers" we find out Mrs. D has been helping Big A all along. In the same episode we see CeCe wearing the clothes bought by Mrs. D in the previous episode. THE BIGGEST CLUE OF ALL.
Season 5 starts with CeCe showing up in NY and then leaving as Vivian Darkbloom. When she left they recreated the Holly scene from Breakfast at Tiffany's. Edith Piaf playing in the background. Whenever they investigated
Varjak in 5B,
Edith Piaf started to play.
After CeCe left in 5x01 there were 5 full episodes with no 'A'. Then we see somebody moving back.
5x12 we see Mona being kidnapped by looking exactly like Ali from the behind.
5x13 CeCe comes to the Christmas party convincing Ali that the PLLs are bad and they make a secret plan to leave using Cindy and Mindy as decoys. Then the next scene 'A' is in the DiLaurentis house.
AND YET YOU SAY CECE WASN'T PLANNED. SERIOUSLY????
