More I think, more I consider this entire story an absurd! If Wille known the passage to Lilith and had supplies prepared, why not just exploded everything in those years? Or filled with traps and explosives? Wille cannot have committed such negligence! Everything from detecting the activation of Unit 13 (which should be impossible since Mark 09 was undetectable, then Eva 13 also should be), until the appearance of Asuka and Mari and the substitution/transformation of Spears seemed staged. For me, Gendo has a double agent infiltrated Wille that monitors and, when is appropriate to Gendo, give information to them. I'm heavy speculating, but I think those who exchanged the spears were Wille and they used the two Spears of Longinius to ensure that Eva 06 and Lilith stay neutralized with Intel of Gendo. This would explain the similarity of Heat Spear with Spear of Cassius.
Kaworu might not know the other entrance and so was for the long way. His delay was beneficial for Wille and more important for Gendo. As always. Gendo = Gary Stu in eternal God Mode.
I didn't say that WILLE installed this gear years ago on the off chance that someday they will have to ambush someone, simply that they arrived a little before EVA-13 and Mark.09 :
- EVA-13 activate, WILLE detect it and the Wunder was probably around the place since some time to be ready to intervene.
- EVA-13 and Mark.09 descend slowly the kilometers of the Main Shaft going from the altar to the Lid near the center of the Black Moon, and seeing the size of the thing when it emerged, the visible part of the Main Shaft must make at most a third of the total distance. It probably took hours to the neo-NERV team to descend. At roughly the same time, the Wunder airdrop EVA 02 and 08 with climbing gear and various weapons(the giant fighter jet probably carrying the heavy material) directly inside the Geofront through the giant cross-shaped crack, the Wunder had probably scanned the place beforehand to find an access.
- Mari and Asuka manage to reach the access before neo-NERV team(maybe 20-30 minutes before) and install their gear to be ready to ambush them(sniper nest, containers...)
- neo-NERV team arrive through the now broken lid, Asuka begin the ambush and the rest is history.
Nothing too far fetched.
They had the DSS Choker inside Eva-13 that monitor the pilot's synchronization.
What an idiot I'm!
I completely forgot that the DSS Choker had a function to monitor the wearer's synchronization with an EVA!
