Final answer:
If Flora saw the ghost and was in league with it, there could be several reasons why she pretended to have seen nothing.
Step-by-step explanation:
If Flora saw the ghost and was in league with it, it is possible that she pretended to have seen nothing for several reasons. One reason could be fear - she may have been too scared to admit that she saw the ghost. Another reason could be a desire to protect herself - if she was involved with the ghost in some way, she may have wanted to distance herself from it to avoid suspicion or trouble. Additionally, she may have pretended to have seen nothing to avoid causing alarm or panic among others who may have been present.
