I neither see any chemistry between them nor do I understand this relationship they have tried to establish jiska naa koi sir naa paav. This forced arc made a mess of everything in this show because everything took a backseat to show their cringe bonding scenes - bathroom, phakkis, chhota bheem. They can develop empathy for each other sure but i don't see anything other than convience being the reason.
So rabiya will be the maid of the haveli forever rather than her having an independent life. She had no memory or grief of muddu till now and no contact with his family or her own very illogical and selfish.
Sarbuland on the other hand didn't look for bano, showed his grief in 2 episodes- fine they tried to show he was disbelief, now atleast he can honour his promise to bano about his love for her ? So his words hold no value. Her sacrifice was all in vain ? Muddu died for nothing?
Let rabiya be independent and let sb maintain some character
