Great Barn/Ang scene, and JF was glad to sink his fangs into some good writing clearly. He got across the accumulated bitterness very well. I've been thinking of pre-vampire Barnabas and present Barnabas as entirely different people, but they're combined here, with the feelings of 1795 Barnabas expressed by his bitter, stern, unmoveable 1968 version. It's so strange for a very good, smart episode like this to pop up in the midst of the tacky carnival ride that is 1968. Sam Hall is credited, showing once again that credits don't give us any information in this storyline. Violet Welles maybe?
There was a lot for all the actors to do and shine with. Louis Edmonds in particular seemed enthusiastic and relieved to have the fetters off, and be allowed to do some real work.
Cass ages again, with the exact same aging appearance as last time. It's good to see her desperate and pushed to her limit. It's always interesting when Barnabas and Julia need to confer on the spot, over something that has to be acted on that second, but can't because others are in the room. He's wondering whether Julia is going to slaughter Ang right there, right now, on the pretext of examining her, though presumably not with the gun, which I think Barnabas took from her anyway. You can tell he figures a doctor could find a quiet way to do it anyway... all this stuff is going on, without our needing anyone to say it. I would not put it beyond Julia at this point just to shoot her dead with the gun on the spot, consequences be damned, if she had it. Her nerves may be frayed beyond endurance. Science offers a promise of controlling a situation, while with the supernatural everything's up for grabs and beyond any of her expertise.
