Teresa Agnes: Gally has everyone convinced that you’re the reason all this has happened.

Thomas: Well, he’s been right so far.

Minho: What are you talking about?

Thomas: This place… it’s not what we thought it was. It’s not a prison, it’s a test. It all started when we were kids. They would give us these challenges. They were experimenting on us. And then people started disappearing. Every month, one after the other, like clockwork.

Newt: They were sending them up into the maze.

Thomas: Yeah, but not all of us.

Newt: What do you mean?

Thomas: Guys, I’m one of them. The people who put you here, I worked with them. I watched you guys for years. The entire time you have been here… I was on the other side of it. So were you. Teresa, we did this to them.
