With the way the music was playing, I didn't even realize that a few vehicles had strolled in—and more seemed to be coming at the moment and much later—though the ones who had just walked into the main hall were a family of four followed by a 3-man group that seemed to be their security detail.
And if it wasn't already obvious, they all looked to be a little tense—even more when Sal approached them and offered her greetings.
But yeah, Sal didn't need to display the reinforcements she had to these people at this very moment though she quickly walked them over to Elsa and Mauro who were having a pretty nice and sweet chat by themselves.
We could barely hear what they were talking about earlier but seeing Mauro's facial expression change when they were disturbed was enough for this poor family and their bodyguards to shake on their boots.
