Why did he kill Teresa and presumably Derek as well. If he was the killer, his motives for helping the others really doesn't make any sense. I know we never got any resolution which makes things even more confusing but I don't know how the writers would've even tried to explain it.
"Weird is just a side effect of being awesome."
I think I get it now.
Thayer thought Derek intentionally tried to kill Sutton so he went to confront him and killed him thinking that he was protecting her and Emma.
He later realizes it was an accident but still feels sort of justified because he did nearly kill the girl he loved.
He sees Ethan and Sutton run away together to escape the law and he knows they're getting close again so he secretly calls Alec giving up Ethan's location.
He knows Alec visited Derek previously and even has a picture which he sends to Rebecca. Even though he knows he didn't commit the crime, he did blackmail Derek into going after Sutton and could potentially be a bigger threat so he likely belongs there anyway.
Teresa figures out the truth and at this point is already messed up by his previous actions and in a desperate moment kills her too. After being rejected by Emma, he resented her and it pushed him over the edge.
"Weird is just a side effect of being awesome."
We didn't know for sure if he killed her or not. This show much like Pretty Little liars had lots of red herrings.
Save the date: December 31, 2014 is Cassie's big day!!! [love6]
Something Alec said about protecting those you love has me thinking that Thayer was hiding the murder weapon to protect the person he thought had killed Theresa--probably Emma or Mads.
shareHe was "protecting" Sutton. Derek was a risk, and in order to keep his beloved Sutton safe he killed him.mhe killed Theresa because she was on to the secret.
