here is some food for thought ... to take the discussion forward ..
wad do u think will go wrong ab se ?
1. it will all start comically for Geet, but Maan will not understand why Geet is taking it so lightly when its about her life and the fact that its in danger .. he turns over protective towards her and they end up fighting over petty issues just before the shaadi ...
2. Anwesha is kidnapped by Brij once he learns she is Maan's sister in ransom for his own sister and threatens to kill her ...
3. Geet's life could be in danger and and she gets badly attacked and in the process loses the baby ..
4. Brij hates Maan, Arjun hates Maan, Maan hates Brij and Arjun but, its not even like either of them want to team up together for the benefit of the other, and in the process there is a three way enemity brewing creating more confusion ...
5. Geet see's Brij, but she doesnt want to bother Maan, since she thinks he is already hassled about it, in the process she ends up messing things up with Maan as well.. she once more thinks its her battle and she is the only one who can tackle him and teach him a lesson in her own way .. she manages as well.. she turns out to be the dark horse ..
6. Geet realises Arjun is not a bad guy after all, and Arjun realises Geet is innocent as well, she decides to support Arjun and Annie, and this leads to a huge conflict, Arjun is actually trying to help Maan, but looks like the bad guy in the process, he leads Maan into believing he is the culprit and hence leaves clues for him to reach Brij and teach him a lesson ..
7. maan realises its Brij on the prowl and he doesnt want Geet to know about it... but Geet already does.. both of them think of the other person's well being... Arjun see's this and decides to take advantage of the situation but his road block is Anwesha as he realises he actually loves her... if he teaches Maan and lesson he loses Anwesha once and for all.. He is in a fix ..
8. Brij does a total turn around towards the end, as his andar ki rooh jaagos or Darji himself turns up with the family towards the end and tells him he has realised he misses his child and it was in her absence that he realised it was she who is more important than the family honor .. happy family reunion- Brij is forced to accept sabke saamne but he vows to take revenge later..
9. NT makes a come back, and Arjun turns into a total dark guy, deadlier than Brij, now this is an impossiblity ... but why rule it out... Anwesha also shows her evil side and she sides Arjun instead of Maan ( well, well, last point hai toh my mind is going the K way thanks to my sleep ...maaf karo )
These are some thoughts ... You could elaborate and add as well...
