Then the tramp took the jewels.
And then, what he did?

He returned to the window,
but it was frightened by the Countess,
He slipped and he fell.

And the necklace?

The necklace ... he dropped it,


so is return back here to take it.

Wait a minute!

I got it!

- Voilα!
- Green against the green.

I don't know if this will help you a lot, cause is a subtitle and is not a full text.

Anyway I really thank you that you took a look at this.

Not an idiom, a statement of fact: The necklace was made from emeralds and had fallen onto a green surface.
