In the event that people spot the Defenders, I suppose they'll either disregard them in the craziness of events or ask questions as to why this particular, unfamiliar group is present. They're not your typical unit, so it might ignite those rumours of the E-6 being present somewhere nearby. Combine that with the Novus Ordo and any potential rebels, and we'll certainly have some madness on our hands. But we'll cross these paths as and when they come.
Well, I'd say Octavia is good where she is, just so long as ORB doesn't wander off. ;)
