It was pleasant to see Roxanne fingering the right culprit. And Barnabas must have felt very strange when he said Angelique was his mother. Of course that would mean that Angelique would be Julia's mother, too. What a lovely, united family!
The other day, when Daphne found Joanna's purse in the drawing room, Judah/Gerard was there. Did he not believe that Joanna's spirit was there? Whether or not Joanna's spirit is there, I think he should have investigated the matter. A ghost at Collinwood could cause problems for him.
Angelique is absolutely convinced that Quentin is Judah. I'm surprised she thinks Judah can be so easily taken care of, but I suppose she figures if it could be done in 1692, it could be done in 1840, too.
