Ahem.
The theory that the Vishnans and Shivans do not communicate across interdimensional borders does not hold water.
Both are entities that, for the most part, are native to subspace. They occupy the thing that binds universes together, so they very definitely know what is going on across the barrier, as it were.
I think this is a reasonable supposition, but nothing we've seen in the campaigns so far has definitively proven it...except perhaps the fact that Ken was perfectly aware of what happened during Universal Truth.
GB - that's true.
I'm still thinking that the Vs and Ss are following the same Protocol, interpreting it differently. However, I think one of the most important things in understanding the story is to fully understand (if that's possible at all) the hierarchy and relationship between the Vs and Ss. That is key. AoA hints at it quite directly, but I think there's a lot more to it than that. There's one contradiction in the story I found, which might be only me not paying attention close enough: In a discussion, Shiva says only the Ss are eternal, and Vs will fall eventually. One of the nodes however reveals that there's a specific point in time when the Ss came to be, at around half the age of the Milky Way galaxy..or is there something I'm missing?
If that's so, on a cosmic scale, that's not
that long, we're talking billions and billions of years before and after that.
Also, why do the Vs pursue Laporte so viciously through the Nagari network? Because she is identified as a S avatar of sorts? If that's so, was it really Bei that she talked to in the last mission? If yes, I find it very difficult to understand how he couldn't get in touch with the Vs, but interfere with the link between Ken and Laporte.
Daaamn, too many questions

Gief act 4 NAU!!!!
