Bohot na jaiz hai , Sanam usko ghar vaapas aana. Lekin Aahil ke alaawa, koi bi khush nahi usko dekh ke. Nahin Lateef, nahin Khala, aur Sanam2 bilkul bhi nahin...
(This is so unfair , Sanam came back to her house after so long. But other than Aahil, no one is happy to see her. Not Lateef, not Khala, and definitely not Sanam2)
<Practising my Hindi there...>

That house is the complete opposite of a happy place. Neither in season 1,2 or 3... House of Vamps.
Aahil is horrified to see Sanam2 shamelessly announcing herself in front of Jannat, his romantic plans to insinuate her memories back subtly failed epicly.
She announces that she is Sanam, his wife. And he quickly qualifies, She is my second wife, Sanam.
"She is also Sanam, Mr. Aahil ?? Boy, you really love that name, don't you ?"Jannat teases a stone faced Aahil.
<Reminded me of an OS farz and I wrote about his state of two wives named Sanam... But this here wasn't as funny as our story...>
"You sure YOUR name isn't Sanam? If it is, I must start to worry..." she snarkily quips.

Aahil tries to divert her away from Sanam2, but the witch herself offers to show her around. "Come, I'll show you around MY house," she quips with a stabbing look at Aahil...
Aahil just seethingly lets them both pass him.
<Why !? Why let the witch even come even close to Sanam after all his efforts !! This frustrates me. He needs to be really protective of her now. Like, let go of all pretense of propriety, kind of protective.
"Get your paws of Jannat right this instant or you'll have hell to pay !!" would have been a more suitable repose... Not that furious whispering of threats he did out of Jannat's earshot. >
So, Sanam2 shows Jannat around, and silly girl innocently tells her about how Shaad and Aahil met. And how she lost her memories, and trying to recall might endanger her life.

<That's the stupidest doctor's advice I've ever heard!!!>
Hence, Sanam2s convonced that her secret evil deeds to Sanam are still safe, so she can be civil. Lateef and Khala's reaction to seeing Sanam again was most disappointing.
Khala I can understand, she never got on Sanam's good side.
But Lateef? So disappointing.
Sanam2 tries to feed Jannat some paan that she made herself but Aahil stops her. To prove her innocence, she tries to make Lateef and Khala eat but they also refuse. So with dripping melodrama, she eats one herself and brings on the waterworks.
Jannat is contrite with the strange display of house politics. She goes to console the crying Sanam2 and even tells of Aahil for hurting the wife's feelings.

Sab barbad ho jayegi Aahil!!! Everything is going downhill!!
Do something !!
Sanam2 vows to make Aahil's life miserable.
Don't go looking for Jannat in your life. I will make it Jahannam for you...
Elsewhere, Shaad follows Mayor Norjahan Khannum to the Nawab house...
