as far as raman still loves shavun goes it was obvious frm d beg itself nd why blame ekta she nd karan both has said it in d press confrnce itself dat its a love triangle...shagun raman ishu is bound to happn one day or d other.!
thats why i think ishu will fall first;-)
custody case ishu is an outsider nd d day shagun or raman start showering love on ruhi she will start loving them more than ishu nd thats what is gone happn :-|
