Paladin Xander Harkness explained
Harkness arrives as the representative of a stronger Brotherhood chapter just as Quintus is trying to build an alliance against that outside authority.
That premise is the useful starting point for understanding Paladin Xander Harkness. The series repeatedly places its characters between the identities they inherit and the choices they make when those identities stop working. The details below concentrate on what the released episodes establish on screen rather than filling gaps with fan theories.
It is also useful to separate a character’s stated beliefs from the choices the story actually shows. Fallout is full of institutions that advertise one purpose while pursuing another, so this guide treats dialogue, revealed history and on-screen decisions as different kinds of evidence. When the series leaves a motive uncertain, the summary keeps that uncertainty instead of converting a plausible interpretation into a fact.
