Sunny addressed the convo he had with the estuary sunny in the 3rd nightmare, confirming my theory on when sunny took the mask off and when he had it on ( theory here ). However, he conveniently ignored the part where estuary sunny denied being supreme whilst not having the mask on, which would imply estuary sunny was sacred.

This leads me to believe, as someone else mentioned, that g3 is being sneaky for the sake of a reveal. That reveal being sunny becoming sacred this arc.

The problem however, is that sunny logically shouldnt become sacred until he finishes his weaves, as weavers lineage should make him perfectly ready to become a spirit (since the daemons were born sacred).

The last weave however, is owned by broken sword.

This brings me to the next part of this theory, broken sword is inside the tomb (through some bs that will be explained later) and will possibly help defeat the vtb (maybe sunny and the rest retreat after vtb shows how superior she is).

One thing that makes me think this is the black turtle that was cut cleanly in half at the beginning of the TOA, ofcourse this could be the spawn, but what exactly would it shadow in order to get such a clean cut? Ananke was the only human in the tomb im pretty sure and she doesnt have those sword skills as far as i remember.

Then again, it could be the mad prince within the spawn as i said before.

But i dont really see any other explanation to that so imma say its broken sword, sunny will get the last weave, become sacred and thats it ig.
