Sam had a very bad feeling indeed about whatever was happening here. Unknown spirits could well be wicked, not necessarily bound to loyalty for the Ascended or Accepted - it could mean the both of them harm.

"Are you sure it's wise to talk to it? I think we should just leave." He said to her, looking back behind them to the cave path.
