Since Rhys would have clearance to inspect any of the surrounding ships himself if he wished, Angel could easily find her way on board using the method you suggested in your initial comment!

Another option would be to send her signal through Rhys's own ship, which could result in some basic interfacing with the Company and RAC ships surrounding.

Any information sent over ship telecom would be accessible, though for the most part that only includes routine checks and basic reports of 'all clear'. Conversation aboard RAC cruisers may be more colorful, but we will leave that up to your imagination. She will also be able to discern to which family each security ship is directly reporting. The most, predictably, fall under Kendry control. Land Hyponia is the only outlier, its fleet small but overstaffed.
