Well, I was just thinking what would be going on in baba's mind after hearing Suki's partial confession on Thursday. Here I am assuming baba will put his brains to some use. For all you know he may be completely senile and may not think beyond the fact that his daughter-in-law cannot be the mother. So all my interpretations may be absolutely meaningless. Anyway here goes:
The confession : Suki tells him the baby is hers (which he dismisses off as bakwas). Then she tells him that Prachi may be doing this to save someone's honour, someone's family from breaking.
Now Prachi screamed that she is the mother of Ritwik. Her reason would be to protect the honour of someone in the house. Otherwise there was no need for her to scream that she is the mother.
Possible conclusions that baba can arrive from this information:
-Suki is indeed the mother of Ritwik. Afterall she was recently married and Prachi had a big hand in their marriage so may want to protect their marriage. Suki also has a past with Alaap, which though baba did not believe, he ended up believing far worse of her character after Suki's hotel expose which backfired.
-Alaap is the father of the child. He is Prachi's brother. Maybe baba may think that he had an affair with someone and that lady has dumped the baby on Prachi threatening to expose Alaap. Prachi may have assumed the responsibility because she does not want to break Alaap's marriage. Since his father-in-law is an underworld he can get him killed if he knows he ruined his daughter's life.
- (Now here is one option I like and which will really be hillarious) Ayesha is the mom!!! Prachi is shielding her because she is her sister and does not want to break her marriage with Neev. Then who is the father? How about suspecting it is Milsi, because baba realised that they were close before marriage (what Suki told him after he witnessed Ayesha's reaction in the dandiya dance). What if he thinks that Prachi is trying to protect from Milsi the secret that he is the father while also trying to save Ayesha's marriage? If he assumes the third option his reaction will be really funny to watch. Ayesha afterall the efforts she undertook to make baba aware of the 'truth' will get accused of hiding her baby!!!
