It is thought by the doc, aliyah and bayji that Noor Bano was having an illicit affair with Shaani even though this wasn’t true. Bayji and co simply walked in on Shaani holding Noor Bano. Thus, Noor Bano wanted to apologise to the doc b/c he felt that she was using him to play games with Shaani.
Shaani’s words “aliyah is my wife” confirms Noor Bano’s suspicion that Shaani wants her as a mistress as he still insists on keeping his marriage to aliyah intact. She is being pursued for one thing, hence the comparison to a janwar.
Sister Josephine tells doc about the misunderstanding he had of the whole Shaani-Noor situation. She most likely told doc that Noor Bano loved him and the feelings she had for Shaani was temporary madness lol.
Hope it makes sense…the drama’s dialogues can be open to many interpretations, such is the genius of the writer.
