It's funny how the dice can surprise you--and yet, on reflection, the results make total sense.
My PC is a mage, and quite a formidable one; he's just recently hit 13th  level.  Up until now, though, I haven't had a sidekick.  After some  thought and consultation with my GM, we agreed that it would make sense  for his sidekick to come from a group of Dwarves he helped rescue from  slavery and protected.
The stats turned out VERY nice--two 17's, one of them in the high 90's  and just ripe for bumping up to 18, and a run of solid 10's, 11's, and  12's.  The 17's wound up in Strength and Dexterity, so I started  thinking Fighter/Thief.  His first Quirk was Obsessive (Security,) which  got me picturing him as a taciturn "Troubleshooter" type--a no-nonsense  bodyguard who always has his eye out for potential threats.
That led me to focus on skills related to that sort of job: Observation,  Scrutiny, Detect Traps, and so forth.  The roles for Observation were  VERY nice; for a first level character, he has the eyes of an eagle.
And that's when it hit me.  You see, my mage's main flaw is Myopia--much  to the dismay and concern of his adventuring companions.  He hasn't  Fireballed a friendly target yet, but it's just a matter of time.
And all of a sudden, it makes sense:
The other Dwarves and the character's wife, concerned by his tendency to  walk into things--ambushes, traps, trees--have gotten together and  assigned him his very own seeing-eye Dwarf."
