1st part is if there is only one participation character, can I trigger Shameful display ability?
2nd part is if there are only two ondinary character participating, and one of them is steward, can I trigger Shameful Display ability? (if one of two participation character is dishonored/honored, can I trigger SD ability to dishonor/honor them?)
