Yes i do feel that she is a front winner contestant for winning. Sana FTW 
Meri Pyaari Si Cute Si Princess
...She carries her heart on the sleeves when she is happy and smiling. Her smiling face lights the show for me.
1) She has made me laugh so much throughout the season ......sometimes intentionally and sometimes unintentionally.
2) She is the only person in the house who gels with everyone.....and yeh uska nature hain.
3) Madhurima had shared a beautiful thing about sana.....ki sana uske liye stand leti hain jiska usse lagta hain ki koi stand nahi le raha hain.....jab sab ek ke khilaf bolte hain toh woh saath deti hain jaise she did in madhurima case. That's an amazing quality in itself....koi toh hona chahiya na....she has done something similar when rash was being targeted for kitchen duties.
4) She isnt against anyone to be specific .......still manages to change the game by her flips.....agar sana na ho toh cheeje predictable hoti....she makes the game unpredictable.....at times its all about will sana flip or not.
4) She does things like calling the loosing team members to eat food first......then eat herself.....such things touch your heart.
5) Usne is game mein bina bahut buri tarah lade bhi sabki dhazziyan udayi hain and she has that strength in her that she can take things back and not go mad.
6) She brings entertainment factor the show by making people dress up and dance.....creates imaginary situations.....does filmy stuff.....talks to crows.
7) Woh sorry kehne mein aur dil se forgive karne mein believe rakhti hain. Her fights with anyone dont last for much time. Owns a big heart.
8) Agar koi udas ho.....toh sana usse jaroor poochthi hain......koi pooche na pooche.
9) Woh apne friends ko sahi guide karne ki koshish karti hain......jinta woh samajhti hain.....us hisab se ache points deti hain.
Just posted this on a main forum thread.....thought of sharing here too. ❤️
