A player, 3 June 2010
"Before a player gains Honor from an action or trait that targeted, came from, or was performed by one or more of his or her dishonorable Personalities, the Personality is rehonored and the player does not gain the Honor."
So if I announce, say, Shiro Daidoji's ranged attack while I have a dishonorable personality in my army, and my opponent reacts with Only Actions Speak, can I then choose the dishonorable personality as the performer so that he rehonors and the honor gain never happens? Or will Only Actions Speak's delayed effect negate my honor gain before I can rehonor my personality?

(I)f I announce, say, Shiro Daidoji's ranged attack while I have a dishonorable personality in my army, and my opponent reacts with Only Actions Speak, can I then choose the dishonorable personality as the performer so that he rehonors and the honor gain never happens?
The question is whether Only Actions Speak or the rehonoring rule apply to the honor gain first, so we need to check: http://rules.l5r.com/CE_Timing#Timing_sequence
Only Words Speak creates an "ongoing or continuous effects that negate(s), prevent(s), or substitute(s) the occurrence that defines the trigger," so comes in at step A.
The rehonoring rule (http://rules.l5r.com/CE_Physically_mark ... shonorable) is a triggered rulebook effect, and comes in at step B. So by that point, Only Actions Speak has taken effect, so there is no honor to be gained and thus nothing to rehonor a dishonorable Personality.
