exactly it shld b a teamwrk.manav was tld by kidnapprs to cum alone,stil if arjun wantd to join him he cld hav tld manav,he wil follw him and cum in picture only if he is needed.the funny ting is people r blaming manav cause he dnt took police help,but if he wldnt hav agreed so people wld hav blamd manav being insensitve twrdrs purvi.manav did wat he wld do 4 ovi-teju too,actualy any parent wld do tat.evn savita being so money minded,dintevn once say no 4 it.they r parents 4 u who do anytng 4 their children in dangr.i calld purvi selfish not 4 running but not evn nce tinking abt manav,ofcourse manav arjn cme to save purvi,wld it b fine 4 u if nw manav tkes purvi leavng injurd arjun behind?after all its purvi who has to b safe naI don't think it's a matter of either/or ...Both Manav and Arjun are working together. Both have to be there for different but very important reasons.
I am sure the teamwork for retrieving the handi was a foreshadowing of this.
