I understand the battle cruiser was glassed and all the flood from that contamination was taken care of. But High Chareity went to the arc portal at earth right? And High Chareity was raining chunks of flood… uh flood stuff. Even if the grave mind didn’t want to rain any of it’s self on earth on the way to the Arc (which would have been stupid) I am sure that earth’s atmosphere would have ripped some chunks off on the way to the portal. Was there some massive battle between humans and flood on earth? Were they able to stifle the infection? Or is there some other reason why earth wasn’t literally eaten by the flood?
hmmm… perhaps this will take some thinking…
perhaps during the glassing on Earth, the spores were killed from the excessive heat. Maybe the humans made another vaccine (doubtful).
But correct me if im wrong, I thought only the cruiser ever actually was present INSIDE the atmosphere. That would mean the spores released from high charity would not get close to earth.
I think the spores will die if they can’t find a host. It is a parasite after all and will starve if it can’t find food. Perhaps the FSC virus would become destroyed or it just lays dormant.
Wait, dormant?
MAYBE HALO 5 PLOT??/1/1/??!?!?!?!?/1/!?!
Because the flood can’t survive an environment that was glassed. And that they themselves were also glassed.
I’m not specifically sure if High Charity was anywhere near earth though. My mind is dusty 
I would guess some kind of contaiment protocol was enforced! we also saw covenant cruisers glassing the infected areas of earth. I don’t think the infection got that far.
With high charityI like to think it may have jumped to the arc rather then going through the portal at earth, even that got blown up so I think the only flood threats we have to face is on the other rings.
If High Charity came to Earth to use the portal, Earth should of became infected
Welcome to one of Halo 3’s biggest plot holes.
This isn’t explained. We don’t know how High Charity gets to the Ark. It has two options.
Use the Portal on Earth. This is possible, except that it appeared inside the Citadel Shield, far from where all the other ships exited. And also there is the issue of it passing over Earth. Unless it jumped inside the Portal (size would be tricky), it had plenty of time to deploy forces across the already scattered defenses of Earth. And we never hear about High Charity heading to Earth first.
It can also just jump straight to the Ark. Except after 100,000 years, the Galaxy’s spinning probably would of relocated it a bit. The Gravemind shouldn’t have known its location. And what did he use to propel a massive station into slipspace and get outside the galaxy in reasonable time? Were there even good drives on High Charity? Did High Charity even have efficient power, because you remember it going dark when the Dreadnought separated. Why did no ships chase it?

Why didn’t the Elites who were glassing Installation 05 destroy High Charity?
Thats a definite question too. Why High Charity was even allowed to escape. They probably had enough ships to at least heavily damage any kind of external reactors and power sources, and could bombard other parts of it.
Glassing a Holy Ring to contain the Flood? Glassing the Holy City shouldn’t have been a problem either, especially since the Forerunner artifact that was inside is gone now.

Because plotholes
Even Cortana said “high charity is on it’s way to earth with an army of flood” Seriously one or two chunks of flood stuff and earth should have been wiped out.
The Covenant glassed the area the flood landed in immediately after they landed, thus killing all of the flood (I’m fairly certain)
> The Covenant glassed the area the flood landed in immediately after they landed, thus killing all of the flood (I’m fairly certain)
That was the outbreak from the Cruiser.
We’re referring to High Charity, using the theory that it used the Earth Portal to get to the Ark. In that time, Earth should have been infested. It doesn’t even have to be purposeful, the atmosphere or moving would make chunks disconnect anyway.

Maybe the chunks disconnected in Earth’s atmosphere and, by a HUGE stroke of luck went straight through the portal along with High Charity. The Gravemind may not have wanted to use Flood Dispersal Pods because it’s possible that his reign of power had boundaries, and the Ark’s distance from Earth would have prevented his control over the corresponding Flood forms. He probably would not have wanted another Gravemind to compete over control with. Maybe…
High Charity most likely used intercepted communications from Sangheili and Jiraelhanae warships (They had captured ships remember) and located coordinates of the Ark. Another possibility was that The Gravemind, seen when he truced with J-117, had more pressing matters; stopping the firing of the Halo Array. Therefore, it may be possible that The Flood simply passed by Earth, ignoring it and believing they could take it later. Whats the point taking a planet if you will die two days later?
Thats my opinion.

The second theory fits with my own analysis. Cool!

They would have to be talking about the Portal and Earth.
Unless they grabbed the Cartographer immediately and started throwing around the coordinates… no one would even know the exact location. And if they did, the matter of time is an issue. Unless they used some super slipspace drive that technically shouldn’t be possible on High Charity in this state… they would have needed to start going almost immediately.
And High Charity could have easily dropped a chunk or two off on Earth and continued through the Portal. Remember, if it stops everyone on the Ark… it will have a really hard time getting back. It crashes High Charity and most of the ships were probably hard to reach.
It would have been more logical to do both, which is why it almost doesn’t seem all that likely that it uses the Portal.
High charity had generators that were capable of slipspace travel in the event that dreadnought was cut loose.
So my theory, was that High charity made a jump to earth, destroyed a bunch of ‘flood -Yoink-’ while in mid jump, And landed right next to the portal. Making a split second decision to save the flood and return to earth later, Gravemind orders them into the portal immediately, leaving no time to drip any flood grease, and what did dropped on the glassed area, killing it most likely.
My theory on this

Well the flood can survive without new host’s, food for generation’s. The Halo ring’s were proof of that since they survived quite a bit of time without any contact, parasite’s always find way’s to survive, evolve over time. It’s speculated that human’s were created from Bacteria, that’s all over the Earth so what’s to say the parasite’s can’t do the same? It certainly would change the Earth in some form since some spores will be blown away due to the wind’s, could land anywhere.
On top of that there’s countless flood there were seen on the ring’s, on infected ships that could be anywhere. I personally believe that most of the flood fled after they were pushed back, that even if they were mostly defeated then we still have the possibly threat of the flood outside our galaxy to turn up since the flood origin’s aren’t even from our galaxy.
I guess if High Charity made a precision slip space jump right into the arc portal, then there would be no flood left to fall on earth. Maybe.
> I guess if High Charity made a precision slip space jump right into the arc portal, then there would be no flood left to fall on earth. Maybe.
LOL
It might happen like this:
Gravemind: OK, let’s get Earth, and then go through the Portal.
Random Pure Form: What if we jump directly into the Portal? Won’t that stop us from taking Earth?
Gravemind: DON’T JINX IT!!!
High Charity emerges from slipspace only to find themselves in slipspace again
Gravemind: @#$% IT!!!
Random Pure Form: Uh oh…
Thus there was one less pure form that Chief had to fight to get to Cortana.
