Disha wasn't crying for Inder, she was crying because a very important episode in her life just past without her knowing it had stopped mattering to her. Happens in life, one minute something is so important and a few years down the road you think - heck what was it!
DK crying sometimes is fine but we don't want him to turn into a regular watering can - it sort of loses the impact. Can you imagine Disha going to him to cry on his shoulder and after hearing the story he ends up crying on her shoulder instead !! π
