I'm wondering if there's a few stealthed missile pods in the system waiting to make an arriving Manty fleet look like an Eridani Edict violator, with Audrey there (in a specifically safe location) ready to report on it.
We don't see any text evidence yet that she's leaning McBride's way, but that could plausibly change if she gets a 'front row' seat to any final atrocities.
