I have a question about the treachery card Glimpse of the Underworld.If an investigator draw Glimpse of the Underworld and it be put into play in his threat area, then he decide to trigger its ability to discard GotU and take 1 damage and 1 horror, would he take 1 additional damage or horror? If another investigator help him resolve GotU by triggering the ability, would that investigator only take 1 damage and 1 horror?
