The Flash, Season 4

Barry:
DeVoe, if you wanted to kill me, you could have just electrocuted me on the street. So... I'm here for a reason.

DeVoe:
Yes, Mr. Allen. So that I may teach you. I am, after all, first and foremost, a teacher.

Barry:
All right. Fine. Teach me. But first, I wanna make sure I'm all caught up. You sent your Samuroid after me. You arranged to pull me out of the Speed Force. You made sure that we turned all those people on that bus into metahumans. Why?

DeVoe:
You see, the finer points of my agenda are not part of today's syllabus.

Barry:
Oh, come on, we can squeeze it in. I'm a fast learner.

DeVoe:
Please!! You're about as capable of seeing the breadth of my machinations as an infant mastering multi-variable physics.

Barry:
[scoffs] Wow.

DeVoe:
The lesson I have prepped for today is much more simple. Life 101. There are no happy endings.
