The Main Character Resolve is not connected to the Relationship Story Throughline. You can make connections during the StoryWeaving process, but the Change/Steadfast dynamic is not related to the Relationship Story Throughline.
In regards to the official Dramatica analysis of The Silence of the Lambs, note that these were done 20+ years ago and could probably use some editing/updating in terms of the StoryEncoding given. I agree that the current encoding sounds like it is working with the Story Judgment, but I would attribute that more to the person doing the analysis. And the fact that Dramatica was only 2 years old at that time.
I still believe, however, that Fantasy works as a great Critical Flaw for her–undermining her Experience. It would be nice if someday down the road those Comprehensive Analyses were edited to better reflected the increased understanding of today. Too many times authors new to Dramatica take what is written as the law, instead of looking to the letter of the law. The Fantasy part of her Critical Flaw is more important than the StoryEncoding text.
