Still, Zapp, I must acknowledge that Dopa has a point there. The group had never actually seen the ghosts to know what was normal to them and what wasn't. As far as the group was concerned, they were as bizarre looking and mannered as they could have expected from such a force. What I mean is that in our involvement with both sides of the story, we may have failed to portray a reasonable reaction to the group because we were now focused on the ghosts. Take a second (fifth or sixth) read.
Maybe a hasty exit while they had the chance, instead of all the kissing and hugging would look better.
