The name came to me in a dream

Besides Weyoun, we rarely get to see other Vorta operate. When we meet Kilana, she is faced with an extremely important yet delicate task - to save a dying Founder without letting the Federation get their hands on them. She can't afford to trust Sisko, so she is forced to fall back on her diplomatic training. Disguise her real feelings, smile, put the opposition at ease, and get what she wants without giving anything away.

But it's clear that she is feeling the strain. You can see her fear bleeding through at points. She has real feelings, she just isn't allowing herself to show them. This is likely the most stressful thing she has ever done in any iteration, and yet she is still able to put on an impressive front.

The fact that both Weyoun and Kilana are so skilled at hiding their emotions makes it likely that the Vorta are specifically trained to do this.

With Weyoun, there are moments were you can SEE his training kick in. At one point, he allows himself to forget about his duties and has some fun at the dabo table. He is genuinely happy to the point where he is bouncing and stimming with excitment.

But the fun is cut short when Sisko arrives with a bottle of poisoned wine that had clearly been sent by Dukat. Weyoun, still full of energy, has to pull that all in and press it down. You can watch it happen - his body language closes up and he becomes very still.

He does still get to have a little genuine fun by drinking the poison in front of Dukat and Sisko. The conversation gets to a point where someone might say something damaging if the tension isn't broken, so he breaks it.

Hiding real anger is harder. When Sisko outright refuses to take down the minefield that blocks Dominion ships from coming through the wormhole, Weyoun is actually, sincerely mad about it.

Of course, Sisko doesn't react well to aggression, and Weyoun has to swallow those feelings and put the mask back on.

It only takes a moment, and all his true feelings are wiped away. He's calm and smiling again.

Even when Weyoun does lose his temper, he holds back. The Federation breaks through their lines, Dukat's plan is falling apart, Weyoun feels he's failing in front of his God, and he gives the biggest display of pure emotion we ever see - which is just a light slap of his hand on the table, immediately followed by a self-regulating clasping of his hands behind his back.

It's not much of a tantrum, but for a Vorta he might as well be screaming.

At another point, Weyoun 5 gets lost in thought when presented with some art he can't understand. He talks to Kira about it almost as if she's a friend,

and then has to snap himself out it when he realizes he is actually being vulnerable.

It's also with Kira that Weyoun lets some of his insecurities regarding Odo slip out. He stops her to ask about him,

and you can see his anxiety in the little crease between his eyebrows, the slight sigh he makes before asking his question. This is about what a God thinks of him. He can't quite hide his true feelings.

Kira asks why Weyoun doesn't just talk to Odo directly, and he's so surprised you can see real fear in his eyes. Then he quickly composes himself and masks again,

only dropping it when she's out of sight.

These real emotional responses of the Vorta are much more subtle than their performative ones. They are usually just a twitch of the mouth, a slight crease in the brow, or tension in the neck. Vorta aren't supposed to show their true emotions, so they are kept small.

Real fear

Real happiness
