Lyla and Diggle in “Unfinished Business”

Lyla

You followed me?

Diggle

Well, I wouldn't have had to if you had told me the real reason why we're in Zurich, Lyla.

Lyla

It's not what it looks like.

Diggle

Really? That's good. That's good, because it looks like you just handed over sensitive A.R.G.U.S. intel to a criminal.

Lyla

I thought you'd have a little more faith in me than that.

Diggle

I did until this very moment. Lyla, just... tell me what's going on. The truth.

Lyla

I caught wind of something. Money changing hands that's... bigger than anything we've been up against. I ran it up the chain, but kept getting stymied by the brass. Not enough evidence.

Diggle

What, so you're going behind A.R.G.U.S.'s back?

Lyla

Didn't expect judgment from someone who's spent so much time delivering justice in the shadows.

Diggle

Lyla, that's not what I'm saying. Listen to me. I just... I just can't believe you would hide this from me. After everything we've been through, I thought the one thing we agreed on is that there will be no more secrets between us.

Lyla

I was trying to protect you. I wasn't keeping secrets. You didn't want to take up Oliver's mantle, and I respect that. But being the Director of A.R.G.U.S. has shown me that there is far more evil in the world than people willing to fight it, and... I can't stand around anymore and just watch, Johnny. Sometimes you have to cross the line for the greater good. I would expect you to understand that.
