..... Exactly what you Consider to be 'Changing' a Character and 'Adding To' a Character ???
So with the 3 Power Points what I think is 'Adding To' a Character:
2 Power Points added to the Leaping Power of Zilver Wreker to increase or add to his Leaping Rank from Rank 5 to Rank 7 so he can leap 900 feet instead of 250 feet.
Not Quite Clear if our GM considers this Adding To a Rank or Changing a Rank ???
As for Father Brian O'Brien the 3rd Power Point would be added to Increase his Sidekick Rank from a 6 to a 7 (Again, is this considered Adding To or Changing ???)
Then I would Add To his Skills with the 5 Power Points that an Increase in Rank would provide as follows:
His 4 Skills that are currently a Rank 2 would be increased by Adding To his current Skills [which does Change him, so again Not Quite Clear

]
Vehicle Rank from 2 to Rank 4 = 1 Power Point
Treatment Rank from 2 to Rank 4 = 1 Power Point
Expertise (Military) from 2 to Rank 5 = 1.5 Power Points
Close Combat (Swords) from 2 to Rank 5 = 1.5 Power Points
So Skari-dono, if these additions to my Sidekick are considered Changes instead of Adding To him, then I will just reserve the 3rd Power Point until Zilver Wreker attains another Power Point increase within the game.
Likewise, if you consider the first 2 Power Points to Add To his Leaping Power a Change, then I will reserve those 2 Power Points until such time as he receives a Power Point increase within the game.
Thank You for Clarifying
