Caitlin, Barry and others in “Unfinished Business”

Caitlin

I don't understand. What do Dr. Wells and The Reverse-Flash have to do with each other?

Barry

Um... They're the same person.

Caitlin

That's impossible.

Barry

Look, Caitlin, it took me a long time too, but it's him.

Caitlin

Dr. Wells is a speedster? He's paralyzed.

Joe

Is he, though?

Caitlin

And why would he kill Barry's mother? It doesn't make any sense. Cisco. Say something.

Cisco

I've been having these dreams. Mostly at night, but sometimes during the day. But they don't feel like dreams. They... they feel real.

Barry

What happens in the dream?

Cisco

Dr. Wells is The Reverse-Flash. And... he kills me.
