Caleb was a spineless individual, a liar as testified to by the many, many lies he told Noa. He had no concern for anyone other than himself and that included Sarah. I don't think Noa had any real desire to have a relationship with her father but she was such a weak individual that she pretty much went along with what anyone else persuaded her to do.
I didn't have any real feelings or sympathy for Noa. I couldn't understand her reluctance to testify in her own behalf at the trial and I certainly didn't understand why she didn't explain what really happened, including Marlene's involvement. Since Marlene was a powerful individual it may not have been believed but I just could not understand her willingness to just sit back and do absolutely nothing.
