Swamped

Specifically, she breaks out into song.

It's a little hard to follow at first - it's filled with puns about money, some of which might be double entendres. But the main thrust of it, she wants Mackenzie to invest in her new company. She implies her plan is to make new buildings, and once it gets underway she'll be able to finance an effort to get her title back.

Naturally, Mackenzie sings back his response.

"Talk is cheap, and I should know.
Before I buy, you'll have to show
That this is going to turn a profit.
Otherwise, I'm staying off it."

The lyrics really aren't very good. He's doing what he can with them, though.

You don't pay much attention to Matilda's reply, though. It's something about a guarantee. But you're more focused on the thief, who seems to be doing something behind one of the chairs.

At first you wonder if they're sobbing, disappointed by the crowd's reaction. Until you spot an object in their hand that makes you think something else is going on.
