Funny how we all have our own takes. I felt for Theo because I think in her mind, she wanted to spend time with her sister in LA. However (and this is my take), I believe Theo was hurt because she felt Nell only wanted her there because knew of Theo’s “gift”. She needed to know what really happened to her husband. She thought Theo could help. Otherwise, why would they have had that scene in one of the flashbacks where Nell was fascinated when she witnessed Theo using said “gift”.
