There's another Sutton and her name's Emma. | permalink

C'mon Alec, that's the understatement of the century. It's also the most overdue confession...ever! Poor Dan really lost it this week and I don't blame him one bit. To no one's surprise, the autopsy report revealed that Theresa didn't die in the pool and was killed by blunt force trauma to the head. Hmm, same as Derek. There was also the evidence of limestone under her nails, which placed her at the quarry at the time of death.

So a few weeks back after Theresa first disappeared, Alec told Thayer that everything he was doing was to protect him. That comment set off a lot of alarms with viewers. Then there was also Thayer's shady demeanor, controlling attitude over Emma and violent outbursts with people like Ethan. These past few episode he seemed highly suspicious and now we know why. 

Thayer killed Theresa. Okay, now that we have that answer, the question is why? What did Thayer have against Theresa? Did he also kill Derek?

After much discussion with friends and other TV Fanatic staff members, here is the best theory that I have: Thayer may have killed Theresa because she got Alec out of jail and helped to protect him. Thayer despised Alec and helped put him behind bars in the first place.

Jordan admitted to killing his brother, but who is his brother? Was Derek Rogers related to Jordan? Maybe Rebecca was framing Alec for the murder of Derek in order to protect herself and Jordan. She hated what Alec did by messing up the adoption of her daughters. She wanted her family back together and wanted to win Ted back. Derek's blackmailing was getting in the way. Rebecca could still be the one responsible for Derek's death.

In this line of thinking, Derek and Theresa were killed for different reasons. I can't think of anyone aside from Rebecca or Alec who would want to keep the twins a secret so badly that they would kill for it. Ted didn't even know there was a twin until last week. Sutton wanted to keep Emma in the dark because she was afraid everyone would choose Emma over her.

Did you believe Sutton's sincerity in helping Dan and Ethan this week? Has she joined the good side? 

In order to get all of these answers we need ABC Family to give the green light for the back 10 episodes of The Lying Game. So everyone go out and tweet ABC Family, post on Facebook, write into the show and get yourselves heard. But before you do that, don't forget to hit the comments with your theories and thoughts!
