Cece Drake - Alison DiLaurentis & the "Twin" theory
Okay so there are lots of rumors floating around that Cece Drake is in-fact the one who has a twin. Certain things seem to be pointing in that direction so it could actually be a possibility.
What if Cece does have a twin that she didn't know about? She was locked away in Radley. Remember when Cece checked herself into Radley with Ali's name? Maybe that's when she saw her but thought her name was ALI. So she started stalking Ali thinking it was her twin Cece. Also remember that Jason said he SAW Cece that night when Ali went missing wearing the a top similar to Ali. So what if the twin was watching that night & was waiting for Cece to be alone and instead hit Alison thinking it was Cece? I know it's a little out there but the crumbs seem to be leading somewhere. Again this is ALL speculation. It could also be that the twin found out about Cece and Ali's relationship and got jealous so she had to get rid of Alison.
Bethany Young COULD possibly be this girl. Bethany was 2 years older than the girls so there is NO WAY she could be a twin of any of the 5 girls or anybody else in that class.
In 5.01 when Cece comes to see Alison in New York & she's talking to her you can see her reflection in the mirror practically the whole time. Is this a hint or are they trying to make us think that?
