As the title says can a dishonorable personality rehonor through focus effects like
Discovering a Conspiracy
As a Focus Effect: After this duel ends, if your Personality won it, gain 2 Honor. Battle/Open: Choose your performing unbowed Magistrate and target a Personality: His lord casts him out for treachery. Permanently remove his Clan alignment keywords. Dishonor him. If he is at a battlefield, bow him and choose a player, who gains or loses 1 Honor.
No. Discovering a Conspiracy's trait for focusing fulfills none of the requirements for rehonoring a Personality.
From the rules for Honorable and Dishonorable:
There are a number of ways to rehonor dishonorable Personalities. - Before a player gains one or more points of Honor from an action or trait that targeted, came from, or was performed by one or more of his or her dishonorable Personalities, if rehonoring the Personalities is not one of that action or trait’s effects, the dishonorable Personalities' rehonoring is substituted for the Honor gain; that is, the Honor gain does not occur and the Personality or Personalities are rehonored. (Dishonorable status is checked when the Personality is targeted, etc. For more details, see References).
- Before a player gains Honor from attaching a card to one of his or her dishonorable Personalities, the Personality's rehonoring is substituted for the Honor gain.
- Before a player with one or more dishonorable Personalities in his or her army gains Honor from destroying enemy cards in battle resolution, all such dishonorable Personalities are rehonored, an effect that substitutes for the Honor gain. In a tied battle, all dishonorable Personalities in an army are rehonored before being destroyed, in substitution for their army's leader's Honor gain.
