The Flash, Season 1

Simon Stagg:
Wells. Who the hell let you in here?

Wells:
You been having a party out there?

Simon:
Well, I'm sure you saw on TV. Former employee of mine tried to kill me.

Wells:
Former employee with the ability to replicate... faced off against a man who could move at super speed.

Simon:
You've seen him too, haven't you?

Wells:
Indeed I have.

Simon:
Extraordinary. The power he possesses, it's like... it's like the gods of olds! Like Mercury on Earth! Could you imagine if you could control his power, if you could... if you could harness it, you could change what it means to be human. The man in the red mask is the key, and I'm gonna get him.

Wells:
[takes off his glasses] The man in the red mask. He's called the Flash... or at least he will be one day. [stands up from his wheelchair]

Simon:
What the hell...?

[Wells stabs Stagg in the stomach with a knife]

Wells:
Forgive me, Simon. I worry that you will think this is personal, and it's not. It's just that the man in the red mask, the fastest man alive... he must be kept...

[draws his knife out of Simon's stomach, who falls over dead]

Wells:
... safe.
