I personally feel his drift came due too many reasons like sana talking bad about her dad....he did pointed to her too when she was saying also....then gautam and karthik etc etc. BB asking questions sana playing game with him etc etc.
Drift from her side is due to him saying woh apne maa baap ki nahi hain.....kisi ki bhi nahi hogi....dil ko sabse pyar hua etc etc.
I personally dont feel ViRa se itna issue hain jitna Sim se hain is waqt.......main pehle dislike dislike kehti thi but after this week episodes, i feel its hate ....sid hates asim........till the time she is standing by asim.....her saying ki sid hi sabse imp hain.....main sid ke saath hoon hamesha will fall on deaf ears.......its like your closest friend siding your enemy and saying dil se toh tere saath hoon. Sid is hating it to the core......its all on his face.....he is going mad. The way he was shouting yesterday to asim ki tu kaun hain iske liye bolne waala and sana went silent on it .....even the way asim reacted to it says the two have feelings for each other. Though i dont find sana guilty in this.....because usne apne statements se usse drift kiya......and as she said usse bhi toh koi chahiye ghar mein.....and asim se always have had that sibling type relation. Ab pata nahi kya hoga....god knows.
