And this means ... ?
If it means that you waited 47 whole minutes before you gave up. If it means something else, please elaborate.
Regardless. I haven't played this scenario and I don't have time to go and look it up now, but a golden rule is that the rulebook is true unless there is a card that say something else then the card trumps the rulebook and that card is true until there is another card that say something else and so on.
Also, this is a narrative game that uses diary cards. Like any other diary card game, the effect of a card is only active for as long as the card stays. If another card tell you to discard a card, then that card is no longer active.
