Personally, I think the show should have adressed Eleven as "Jane Ives Hopper" post-Season 2, not just as Jane Hopper. Terry Ives was also a victim of abuse, whose life and daughter were taken from her. Hop's adoption shouldn't erase that part of Jane's identity.
Watching this season, I couldn't help but compare Nancy's development to Carol's from TWD: both went from being two very "innocent" and submissive women, so to speak, to having a fking beast development derived from a loss that marked them (Barb for Nancy, Sophia for Carol).
