The leaving STE (or TSC) fleet almost entirely stops to take in the spectacle.
"Oh my god"
"what the hell is that Thing!
and what will it even do!"
"but if they can build that...
we could rebuild our lost homeworld with tech like that."
"i doubt they will assist us now"
"anyway lets go, we need to be present for the formation of the Second Tau Empire.
We can come back for those Two later."
With that, the Fleet leaves, at this point in the timeline, just before the STE was formed.
