I was watching a couple of episodes this morning, and noticed that Kate Mulgrew reacts to whatever another character says. There are slight changes of expression, as if she's actually listening and forming a reply. Compare her with Garret, who admittedly was less experienced as an actor, and lacked Mulgrew's subtlety of performance.
JRulez, not here LOL! But I was in a huge dust storm once, pretty freaky.
And Melakon ABSOLUTELY TRUE. She's a joy to watch. She's completely engaged in the scene.
