Under the command of Admiral Trench, the Separatists have blockaded Christophsis. The episode starts with the Republic forces' attempt to break through the blockade.
Watching the episode this time, I noticed that Trench's command ship has six eyes painted on it so that the ship itself looks a bit like Trench.
Shortly after this scene, Admiral Yularen identifies Trench via a different marking on the ship:
but the six eyes painted on the prow seem to be an equally distinctive indication of who's commanding the ship.
