Wait a minute... So Angel is just driving them straight to the heart of the Alvarez Empire where Makrov is, as if it were nothing, right after getting close brush with death by the hands of Brandish.

Could it be that she's working with someone within the Empire? Some kind of secessionist or rebel group? Otherwise it sounds like suicide to go into the heart of enemy territory.
