Lyla and Diggle in “Unfinished Business”

Lyla

You're telling me you became the Green Arrow after you knew about the tremor?

Diggle

I was gonna tell Oliver, but then he asked me to take over for him. I couldn't let him down, couldn't let the team down.

Lyla

But you were physically compromised!

Diggle

I came up with a temporary solution, an experimental steroid. Lyla, I wanted to tell you so bad. I know it was the wrong call, I'm sorry.

Lyla

I'm just glad you finally told me.

Diggle

And now that I have, I need your help. Is there anything... anything that A.R.G.U.S. is working on that can help my condition?

Lyla

I thought it was just some kind of steroid.

Diggle

Well, we found out that the manufacturer was involved in, um... criminal activity. He and his crew have killed at least two people, I dunno, maybe more.

Lyla

Right, so your experimental steroid is actually an illegal drug. Look, if this is what it's taken for you to come clean and get this guy off of the street, then I guess I should be grateful. [seeing Diggle's look] What? [Diggle looks away] You're still using the drug. I guess that means that the drug dealer is out there, too.

Diggle

To be Green Arrow means I have to be physically capable protecting this city, no matter what. Lyla, you make the same choices at A.R.G.U.S. all the time.

Lyla

Choices you've condemned me for making!

Diggle

I know I'm wrong, but I couldn't let Oliver down.

Lyla

So you let yourself down instead. Johnny, you are the most moral man I know. I can't even begin to fathom how you could do this.

Diggle

As soon as A.R.G.U.S. has a solution, I will get my guy off the street.

Lyla

And till then, how many more people is this guy going to kill?

Diggle

It's not that simple. It's not that simple!

Lyla

You're the one who taught me that it is.
