It's possible(but not likely) that Flood got inside the Forerunner Ship. Two Flood controlled Pelicans flew over MC. One crashed on the landing platform, while the other...flies out towards the Forerunner Ship. Cortana might've exaggerated the Flood invasion when she said that Flood controlled ships are touching down all over the city. Does she mean the Prophets' Sanctum tower, or the city in the distance? The latter doesn't seem likely. Surely the Flood wouldn't have captured that many aircraft. The vast majority would've have came from In Amber Clad. Unless the Flood hijacked more ships.
In Amber Clad-Since only the commander of the ship has access to its core systems(self destruct, erasing data), I don't think In Amber Clad's databanks were cleared, as Miranda was tied up(literally) at the moment.
Gravemind-He probably knows the coordinates to Earth. If he has controlled Cortana, not to mention he has Regret too, and possibly others. Why would Gravemind choose High Charity? Well..it's the closest thing to infest. Now he has a whole moon-sized battle station at his disposal. If there''s still power within High Charity, then it could be used to make a slipspace jump.
