Somewhere I agree with Pennu here😆😳..I think all the 3 options will come into action one by one but the creatives need to make sure that they all happen in proper order😉😛
See first of all like everyone said let RK b thrown out of the house along with Kullu-Buaji and Chaijee and then let Raj come into terms with the real India and how these britishers r actually torturing the Indians..After this he can start doing mehnat and slowly Kranti can start trusting Rajbir😳..So here your 1st option will come into effect😃
Then your 2nd option might come into effect where Raj too might participate in KK-Activities after facing the real hardships of rural India😳..this will make Kranti realize that finally her husband is a changed man now and also a true Indian by heart😃
After this they need to show how slowly that feeling of love for each other is developing in both their hearts due to various reasons😳,..In this case I will not mind a 2nd tabela also😛
Then in the end they can show Kranti becoming Pregnent😳...So this might come after 6-7 months😉😆,..and finally your 3rd option will also come into effect😃
