Interesting ideas - it's too bad that both the Talosians and the "Normans" got swept under the carpets after the episodes were over. Then again, TOS did that with a few plotlines over the years.
On one hand, the Federation might've recognized that the Talosians could enslave just about anyone if they got off planet, hence the General Order 7. Then again, the Talosians were supposed to have learned that humans hate captivity so much that even if in a "gilded" cage, they make bad pets.
What did they want Pike for in "The Menagerie?" Was it to relieve his suffering, or did they still want to try mating Vina & Pike somehow?
