Very late in the life of "Star Trek: Enterprise" came a wonderful plot idea that make up three very memorable episodes. Part one involves attacks that exacerbate tensions between the Tellurites and Andorians. Here in part two, Malcolm and Trip go on a mission to figure out who is responsible--and they manage to sneak aboard a ship that can imitate other ships! In other words, Romulans are using this strange drone to sow anger and war because they want to destabilize the quadrant. Instead, they manage to unify these enemies because they eventually realize that they are being manipulated.
I liked this plot quite a bit. However, there was a plot involving a debt of honor and a fight to the death that seemed unnecessary and, perhaps, only there to fill out the episode. Still, the show keeps your interest and the Romulans are, as always, enjoyably bad and devious.
