Plot hole? (pls help)

Hey waypoint! I’m wondering if I found a plothole in the story of ODST/Halo 2. Number 1 will be the plothole, (if there is an explanation, please enlighten me) and number 2 is just a quick question. Ok so…

1-I’m playing all the Halo games in order. I started with Reach 1 week before CEA, than I played CEA and moved on to Halo 2, stopped before the level “Delta Halo” and played the reach campaign. Now im on the level Delta Halo. I just wanted to know, did the prophets know the use of the portal on Earth before 343 Guilty Spark said that they had to get to the Ark to activate the array. In other words, it was not till the end of Halo 2 that we knew that the whole array had to be activated at the Ark, so why were the prophets so eager to uncover the portal in New Mombasa if they didn’t even know what it did yet? Plot hole?
(I know its a little hard to understand)

2-Regret’s carrier jumped on October 20th, and came out of slipspace on November 2nd. So why did Miranda Keyes say “sorry for the quick jump” as soon as they came out of slipspace 14 days after they made the jump?

Thanks in advance guys :smiley:

…“Delta Halo” and played the ODST campaign…
Sorry guys. Anways, any answers?

They probably didn’t know what it was under Africa. They have scanners that detect Forerunner tech as shown in the Book “Contact Harvest”. While they wanted to invade Earth they also wanted to dig as they did with Reach, to find any Foreeunner artifacts their scanners had shown.

Also, it’s possible that the Covenant found some clues on Delta Halo that pointed towards an Earth like planet for the location, or maybe there was even a map on the Keyship, and now with the knowledge of Earth they put two and two together.

captured forrunner tech told them the planet was an artifact gold mine.
