I've might have missed something here but...
When a character has a talent, let's say Silver tongue (a Reputataion talent) with his first career.
Later the player decides to do a different career that doesn't have a reputation talent slot.
So far as I can tell, this mean that he looses the ability to use the Silver tongue talent.
To me this does not make sense, that the character looses the use of the Silver tongue talent.
Did I miss a rule somewhere?
And thanks to all for some interesting view points.
