Ashari would provide a basic briefing of the mission and what the incoming team was attempting to do. It may, however, be somewhat garbled by the fact that Ashari is distracted with social/organizational matters. If you want me to provide more information on this front, I can do so, or you can come up with your own, possibly hilariously inaccurate, briefing.

Jedao is available for combat practice, probably under Seyli's supervision.

The mothling situation is not known more broadly in the rebellion. Ashari is unlikely to have bruited that about.
