Two quick questions on what happens when I destroy a dishonored personality.
First: When I destroy a dishonored personality who's base personal honor is 0. Does he not lose any honor or is he considered to lose 0 honor in which this honor loss could be increased with cards like "Denounced on Stage" and "Yogo Honami"?
Second: When a Spider clan player's dishonored personality is destroyed, do they lose the honor for the destruction? Or does their stronghold ability of preventing honor losses from Spider Personalities make it so that the honor loss doesn't take place?

http://rules.l5r.com/The_Player#Family_Honor: "An Honor gain of 0 points is not considered a gain for things that check whether a gain happened. Likewise, an Honor loss of 0 points is not considered a loss for such things."
