Looks like Duncan's twisted master plan may start to come together tonight, as he gives Ellen the poison she must use to kill the president. While Duncan himself, must take out an insider as investigators get nearer to uncovering the conspiracy to kill the president. Elsewhere, as Morgan mourns for Boyd, Sandrine feels guilty about what happened in his final moments (how tense was that?!). Seriously though, maybe everybody should just stop killing each other here? It would surely be a start.
