Hi @johnesan. I interpreted this question that each animal’s statement must match the truth/lie schedule. Taking your Friday example, the lion told the truth on Friday and Thursday per the schedule. So if on Friday he said “I was lying yesterday” 🤥, that does not match the schedule which states that he was telling the truth on Thursday. So if the lion did not meet the criteria, then there is no need to review the unicorn’s statement, and therefore can dismiss Friday as a possible answer.
