I think Goyal has accused Reddy's of sabotage in some newspaper article and the girl's father does not like it He may stall the wedding, saying let us clear up the mess first and get married after 6 months. So roka happens but no marriage.
The way CVs have shown stuff- the possible culprits are:
1, KK
2. karthik
3. Sreeanna
4. Heera
5. Goyal
6. Rao ( thou to a lesser extent)
7. Neeta
From the hints they gave nearing Prabhz death and funeral, it seems Karthik, Sreeanna ( maybe Neeta) and Heera are a team. Karthik winked at Heera during the funeral, got a call talking of Prabz death on his phone and still gets mysterious calls. The Sreeanna Karthik nod during the match before the crash could be taken a clue.
Riddhi does not like Sid and she will keep creating doubts in Anu's mind about Sid's seriousness about her.
Sid however cant be expected to dance to Anu's tunes, though he understands that there is some pressure on Anu to get married!
The only doubt I dont have is that Sid's dulhaniya talk is indeed Anushka - why would anyone doubt that? He waited 7 long years for her just for ditching her now???
The big issue with Sid is how to make him the right choice for Anushka in front of the Reddy's. That is holding him back. he knows he has to grow to make him suitable for Anushka.
The only thing is Uday said the love story will get intense. I am hoping Vedant will bring about the intensity and the push that is needed since the murder mystrey will always get precedence over everything else.
one thing is that Sid knows for sure that the ariline is sabotage and murders have surely happened. So he cant focus on romance . Anu is unaware hence the issue... if she knows what is in his mind, she will work with him... she love Prabz too.
