Thomas is officially the most idiotic protagonist ever. Not only he can't grasp the concept of secrecy at all, blurting out everything about who he is and what he knows to everyone he meets, but he is not even able to extract back some information for himself on the contrary, every time someone tries to give him some valuable piece of knowledge he stops them saying he doesn't want to know. What?!? You don't want to know? Really?!? If this is the way the author thinks suspense is kept to high levels, he'd better think again. 
 Besides why on earth Brenda and Gally, who betrayed him because they were manipulated by WICKED are still trustworthy but Teresa for exactly the same reason is not?
