why is the old tulsi bak?

I was soo excited when I found out that Smriti was coming back because this serial felt incomplete without her, and now that she is back (I know it's been only two epi's) but either ways they hardly show her and the story is going off into a boring track about money and property, they haven't even shown mihir, and when the trio (old tulsi, fake tulsi and mandira) were celebrating i swear it looked like it was the old tulsi's body double again, why would they bring her back if they were hardly going to show her and even when they did show her it was just her body double, plus the track slowed down even more since she came back...I know it's still really early but still, right now they had everyone's attention and the trps were really high, now would be a time to bring her back with a big bang and get everyone hooked, and keep them hooked...
