Anwar and his daughter Xanther's relationship. They have a strong and warm father-child bond, and he is a strong and encouraging figure in her life (which, seeing all her health issues, you really wish upon her).
Also Anwar and Dov's relationship - his wife Astair's ex, and Xanther's biological father. Rather than any animosity between them, which would frequently happen in these kind of family situations (especially since Astair got together with Anwar when she was pregnant with Xanther by Dov), there is only mutual respect and understanding between them.
