I adored Professor Stokes and every other incarnation of Thayer David's on DS.
Ben is kind, gentle, ill-used by both Angelique and Barnabas, yet he maintains his dignity and concern for the Collins faily. Even when we see him in 1840, he assists Julia and ends up with an undeserved fate.
The erudite Professor Stokes was a joy to watch, too. Julia and Barnabas needed someone to help them fight supernatural demons, and Stokes fit the bill nicely. I often wish they had confided in him about Barnabas' little problem, but I suspect he figured it out on his own, anyway.
Count Petofi wasn't amongst my favorite characters, but that's because Thayer David brought him to such vivid life. You had to admire the erudite way the Count lived his life, but he was a flawed magician for sure, and Thayer David portrayed him brilliantly.
Love, Robin
