"Red coat" aka bigA

We have been told by producers that the person in the red coat will be revealed in the season finale march 19th. Lately a "girl" in a red coat (assumed to be the leader) has been seen by the liars on a few ocasions.

 

In episode 19 "What becomes of the broken hearted" we saw two members of the A-team placing for bottles of whiskey with each little liars face on it. They placed an empty bottle in the middle and spun it. The bottle first stoped at Arias picture but one member of the A-team changed the direction of which the bottle was pointing at so it pointed to the bottle with Spencer's picture instead. I believe this gave us a big clue about the leader and not just about which girl they are targeting.

 

 

 

I believe that the empty bottle in the middle represents Alison (the bottle is empty-Alison is dead). And for the fact that the bottle determines which liar becomes the new target shows that Alison is in charge one way or another. I believe that bigA is someone who used to hate Alison because he/she was jealous of her and he/she wanted to be her. After Alison died this person saw the opportunity to become the new Alison and bigA built a team consisting of people who hated Alison. A has targeted Spencer really much and that's something Alison would do because Spencer was the only one who stud up to her and actually said what she thought. 

 

In an interview Troian Bellisario said “There’s something about the ‘Red Coat’ that they all recognize as part of their past.” Which could hint that bigA looks like Alison which is a big part of their past. I think bigA wears a blonde wig for most of the time and has an Alison mask on. I don't even think the other members of the A-team know who bigA really is and that's maybe why Mona saw Alison in a red coat at Radley smiling at her like she was proud, think about it Alison never had an red coat on without a black wig and Mona saw her without a wig maybe it was bigA but because bigA looks like Alison Mona saw Ali.
