Don't expect the makers to think so thoroughly as you guys do, so that is why I don't expect any logic
The only way they will prove Suraj innocent is by DNA test...common thing in serials and finish the matter off...
And as someone earlier mentioned, there will be confession first, before the dhamaka will come, otherwise the promo cannot fit anywhere.
And going by what I read ( spoilers ) is that Chakor will confess first, don't know if Suraj does too, but what we never wanted , has ultimately happened. We always wanted Suraj to take the first step, move heaven and earth for her, but unfortunately nothing of that sort. For a guy who declared his love so passionately before, this time around he seems pretty pheeka ( at least to me )
And they have been building something very big up it seems: Chakor trusting Suraj completely, sharing whatever happens, proposes first, confesses first...acc to spoilers she will still stand by Suraj...it almost seems like the biggest heartbreak is on the way for her...can also be wrong though
So lets see what happens after this pregnancy revelation
