i think madhav might be a opposition lawyer...since nachikhet will break the engagement with nive...the venomous snake will spit her poison...she will want revenge and her first move is separating suhani from Neira as she is the strength of their relationship thats when ronnie will come into the picture to claim custody of suhani...Neira will be shattered...especially nachikhet who will do anything for suhani...ragini will be father-daughter duo strength...nive might fight ronnie's case on request...well everything is plotted and plan by nive...i feel this madhav guy might be a lawyer too who will fight suhani's custody case for Neira...maybe he is a friend of nachikhet...or a build up will made where madhav-ragini met by coincidence...ragini doesn't know he is a lawyer...there will be a friendship bond b/w madhav-ragini...the custody case comes up...ragini might get to know that madhav is a lawyer...she will request him to fight the custody case of her daughter...madhav will agree to it and takes up the case for ragini...
madhav turning grey...negative are later stages...currently he needs to be positive in entering Neira's lives...i think on this lines...that maybe madhav is a lawyer who will fight suhani's case...its very evident that after MU are cleared...ragini-suhani bond is going to get strong...a bond that noone can break...ragini loves suhani alot...she will definitely not want her daughter...the angel of her life to leave her and she knows nachikhet will be broken if suhani leaves him...he will not bear the pain of his daughter being separated from him...ragini will take the matter in her hands...madhav might help her...
well its my thought only...thats how i think madhav character fits in...otherwise his character entry doesn't make sense...
