I think zara will insist to stay with Indu as she has entered in SN to protect her and both Khan and Rishi will agree for it. Seher may be shifted to Ishan's or Munn'a room.or Mr. khan has to leave delhi for some work and zara will stay in barasati.
up til now Rahil has introduced himself as MR. Khan and not malik khan in serial. we know he is malik khan and Zara'a husband from articles and not in serial. zara may have asked Mr. khan's help to enter in SN and requested him to pretend as her husband. she has told her officer's that some how she will manage to enter in SN. Malik may be Zara'sfather's name.
Then Zara will reveal that khan is terrorist and will save Indu. and Indu will change her opinion about her from 'Khdus Aunt to good friend. on 11th only rishi ,viewers and perhaps munna or Indar will come to know that Zara is indira . then Indu will come to know that Indira is her real mother. and evil did of shweta. she may be shocked and suffered but Rishi and Zara will give support to her.
and then every body will come to know that Zara is Indira .
or shweta and Zara will together will save Indu from terrorist and in that shweta may die. and indira has to struggle to win Indu.
The body which is put on fire may be reals zara's body.
If they show zara is not Indira then let them vacc**t 8-30 slot for Qbul hai. no indira no hitler didi. they can not change hitler didi .it's indira only'
ready to accept any blooper ,fantasy unreal situation to prove Zara is Indira
