One point I'm willing to concede is that Pritchart's willingness to "fire the first shot" proves handy even to Manticore, when she decides to use her own wallers against the SLN, effectively putting Haven at war with the League.
(even though, technically, Filareta is given the chance to stand down).
Which I'm only saying to underscore that these characters, with different attitudes and "guilt baggages", do serve the story well in a neatly "coordinated" arc.
