I don't Think They will Sonia's Re-Entry and she Trying to Cause problem In Ragvir Marriage,Then There will Be no difference B/w Bidaai and any other Serial(espicially Kekta's).
They Can Show after Ragvir's Marraige ,Vasu's Rude Attitude towards Both Ragini-Sadhana and Both Ranvir-Alekh Protesting Vasu(now If Vasu Agree For Marriage It will Be 100 % without Her Wish).
Then They Can show Alekh's Mystery and his road to Recovery,I'm sure They will Show Ragvir and Sadhana Helping Alekh in That ,That will Also be High Point In Bidaai.
According to Me High Points In Biddai Till Now Are
1)Ragini Decides Not to Marry On The D-Day with Puneet.
2)Introduction Of Rajnash Family.
3)Sadhana's Condition To Vasu and Her Marriage with Alekh.
4)Ranvir's Re-entry With Sonia.
5)Sadhana Revealing Sonia's True Colour On Engagement Day.
6)Ragvir's First Phone convo AccidenTly.
7) Ragvir's Unconditional Love Without Seeing Each other.
8)Taj Mahotsav.
9)Ranvir's Realisation Of his loVe .
10)Ranvir's Confession.
11)Ragini Sacrifising Her Love .
12)Ranvir Proving Vineet innocent.
13)Shisir Refusing to Get Engaged as He Saw true Love Of Ragvir.
14)Mamaji Calling Rajvansh Family to Talk about Ragvir Realation
