Dr. Harrison Wells: You're incredibly clever, Cisco. I've always said so.
Cisco Ramon: You're him, the Reverse-Flash.
Dr. Harrison Wells: You and I haven't been truly, properly introduced. I am Eobard Thawne.
Cisco Ramon: Thawne? Like Eddie.
Dr. Harrison Wells: Let's call him a distant relative.
Cisco Ramon: The night that we trapped the Reverse-Flash, you almost died.
Dr. Harrison Wells: Mm-hm.
Cisco Ramon: There were two of you.
Dr. Harrison Wells: It's an after-image. A speed mirage, if you will.
Cisco Ramon: Joe was right. You were there that night, fifteen years ago, in Barry's house. You killed Nora Allen.
Dr. Harrison Wells: It was never my intention to kill Nora. I was there to kill Barry.
Cisco Ramon: Why? You're his friend. You've been teaching him how to...
Dr. Harrison Wells: ...go faster, I know. A means to an end, and I'll tell you why. Because I have been stuck here, marooned here in this place for fifteen long years, and The Flash, and The Flash's speed, is the key to my returning to my world, to my time, and no one is going to prevent that from happening.
Cisco Ramon: I can help you.
Dr. Harrison Wells: You're smart, Cisco, but you're not that smart. Do you know how hard it has been to keep all of this from you, especially from you? Because the truth is I've grown quite fond of you, and in many ways, you have shown me what it's like to have a son. Forgive me, but to me, you've been dead for centuries.
