new lead

so as we all know about the bad news .

Well obviously they will be looking for a male lead to play the older karthik, whereas with sonal playing the older khushi they will surely bring in a male lead to star opposite sonal. Not sure who they will choose though. Will tai also be killing her own children too, considering it is said that apart from rinku and sonal, everyone else's character will be killed?

ya and even bindu and paayara also ??
