Noon Job, Boot: Mark your home. If successful, search your discard pile for a Horse and attach it to any one of your dudes, reducing its cost by 1.
This question applies to Francisco Rosales and is not applicable to Maggie Harris since she targets your home.
Noon Job, Boot: Mark the Town Square. If successful, search your discard pile for a Sidekick or Horse and attach it to one of your dudes, reducing its cost by 2.
React, Boot: After this dude’s posse succeeds at a job that didn’t mark your home, this dude stays at this location instead of going home booted.
The scenario answer is detailed as follows:
Step 5. Is the Job Done?
If the leader’s posse wins the shootout, or no player forms a defending posse, the job succeeds.
(At this time you can react with a Quarter Horse already in play)
Otherwise, the job fails. After the shootout ends, regardless of the outcome, survivors in the leader’s posse go home booted. Surviving dudes in the defending posse stay where they are.
Now resolve the effects of a successful job as given on the card, assuming the mark is still in play.
(At this time you would search for Quarter Horse and are past the point where your dudes are back home)
If not, the job succeeds anyway but the mark is unaffected. If the job fails, nothing happens. Finally, the remaining posses are dissolved and the job ends.
