I agree. I think Teresa is enjoying herself as the victim. I think she's made that jump from "it's not me, it's just a character" and she's brought more fun to the role.
I gave a really thorough description to White Rose as to how Dr. Squalus should be played when I did the first "Body Donor" film with her and Victoria, and she picked it up immediately. It took a couple of films for her and Teresa to get comfortable with each other as actors, and for Teresa to figure out how she wanted to play the victim. The only direction I give to the actor playing the victim is "Don't scream or cry. Be strong. Be a warrior." And they go from there.
Teresa recently did another crucifixion video (that makes two by my count). I'm thinking my next "Body Donor" film will be a medical crucifixion with her being sacrificed for the sake of scientific study. There's a cross mounted on the wall directly behind her in this video, so it dovetails nicely.
