I'll add a few cheeky hints myself.
The aliens have been nigh on ignoring Borealis with the Battle Dish modifications active, mostly because one pulse from the dish would have shot one of their ships out the sky. With the dish gone they had to investigate to see if they couldn't either 1. See what modifications had been done to the dish and 2. Check to see if it really was destroyed.
Okay, here's a few bits:
a) the device under the dish was not kyr'ozch in origin.
b) Bahirae was attacked at the dish by the obsidian army individuals just like many others.
c) isn't it just a tiny bit curious how the sentinels haven't said much in all this about the blatant invasion of Tir?
d) Bahirae's entire history is yet to be fully revealed, what is known so far is she's part of the Ares Project to give her immense tactical knowledge and that she's already taken part in omni-pol ops. By 29487, she is a part of omni-af, even if she is quoted as a portable asset.
