i know everybody is wonderin when will karan-nandini son will appear in this show,
I DONT KNOW REALLY MYSELF,
but all i can say that you guys should have patience, becoz if you think other characters were introduced later after the leap for example:
PREM- KZK his charcter was introduced 10 months after the leap, thats almost a year
Karan-Kyunki he was introducd 4 months afterthe leap(i think)
Ansh- Kyunki he was introduced about 10 months as well(i think)
Eklavya-Kyunki entered the show about 3 months time
so all i can ay to you guys is that to have patience KARAN-NANDINI KID will enter the show, i would say another 3 months. (prediction)
