I think after the whole abha fiasco they would show Karan and abha working togther bu NO obviously Karan doesn't agree with abha. While she is away the marriage of yasho and jaggu will be in full prep. Abha meets prats after learning some truth in Delhi. Abha will bring prats home but no one will accept her except for dadi and will push yasho-jaggu wedding. Then on the day of the marriage Karan will come to know the trutth and will ask abha and his mom to forgive him.
Then to make it up to them he will again take them on a holiday! Seriously!! Karan Can have some more brains than that!
