The question should be,
Why on earth Neil will video call Isha?
Why on earth they will send Neil out of Delhi if their target is Isha?
It doesn't make sense
They will be conscious about Neil's whereabouts only if their target is Yuvika.
Neil se Isha ka Kya Lena Dena 

He didn't protect her in fire sequence and he'll be the perpetrator in VH
