After analyzing the first week, i feel she is the smartest player of the house. Just like Tanna & Gautam she too looks as if participating after ltaking coaching classes from previous seasons. If Gautam made the mistake & faked a bit to hide his real self, Tanna's over-worked dimaag made her a strategy maker from the very beginning. But Soni is silently playing her game by becoming a friend of all.
She was lucky that she got promoted to business class. Two three times (on live feed) i noticed Arya, Tanna, Upen, Minisha, Praneet & Soni on deep discussion inside the business class cabin which helped her in becoming a part of the group. Later we saw her making an entry on kitchen as roti maker. While Tanna gained all attention with her bossy nature, she stood there without being loud but also gelling with the cooking team by making side comments about everything. Then we all saw her & Tanna discussing about eliminations which revealed Tanna's as well as her crooked side.
She made Arya her brother & Sukku her friend. She is also friendly with all the other housemates. The only person she criticized openly was Sonali coz the nomination procedure was open & there was no way hiding. Sonali was after Arya after nominations and didnt give any importance that Soni nominated her. But Soni's back-bitching side was revealed when Salman played an unseen video for us & Sonali. With Sukku becoming a target for Sonali, Soni got saved again.
So friends, IMO she is playing safe by pretending to be a friend of all. What say?
PS: I'm a neutral viewer. Not a Soni fan or hater.
