Raven is the only Host with an alien symbiosis that can board the Streamer, what makes her so special? She's not the only one with innovations, but someone has to make the ultimate sacrifice sooner or later. The Orb-Univerous are beginning to divide even rebel amongst themselves, the crew on the Streamer must make sure this continues to happen if they want to take earth back, but they will at least try to take one city and free it from all aliens. In the end someone was going to have the best of both sides. Or worst!
