I know it's evil of me but i want him to get misty eyed after he gets to the reason behind her joining the contest.
Like he will start feeling utterly guilty for yelling at her and then pulling her in this big tight hug, because Twinkle tu itni achieve kyu hai. Because kabhi apne baare main bhi soocha kar. Because you are the best wife I could ever ask for and i never want us to be over. Because thank you and because sorry.
And twinkle will just run her hand through his hair and say...humari family ke liye main kuch bhi seh sakti hoon. Its all for you.
