This is just my assumption not related to any spoiler
Im Anikas Fan but i did miss initial episodes so downloaded most of old episodes to watch shivika
While watching old episodes i got few doubts
I think the insider is Tia,This is my theory though im not sure about het actual motive
Tia allowed someone to enter into oberoi mansion right
The person looked like a man while entering but when anika interrupted and brought tia out of car,the intruder hided behind a tree and it was a women not a man
It looked more like shwetalana bcz gayatri is too slim and roop is too fat
May be cvs can show later it as gayathri too as they might have used body double.
When Tia felt she was caught she said game is over.what game?
Other one when shivay was thought to be dead ridhima and even ishana came to oberoi house where was tia
Tia only came later after an hour of shivay came bacj
Ur fiance is declared dead and u even get news on tv abt his chopper blast but u didnt care to even go to his home or contact his family.she only went when she got news or scoop that shivay was back.
Another one in cocktail party bfr shivika dance om rudra soumya mallika and priyanka were out on floor
Bfr shivika in that glimpse of them tia was missing
So where was she
Bfr tat shivika confession gayatri didnt had code
But after that gayatri got the code somehow how?
Bcz Tia was awake she wasnt drunk at all tat was the reason when mallika questioned tia abt shitia first meeting,she fooled mallika with her universe nonsense.
So that day Tia searched for something in Mansion when all were drunk n other family members werent present
Tia might have even got her partner inside the mansion on party night and they might have searched for locker room or code or any files
Other thing abt that gas leak,how did that fruit basket reached to oberoi mansion.may be tia helped
After the accident and pooja what did Tia do tia was like selfie
Who does take a selfie after such accident
How did gayatri know her plan failed bcz she had seen that pic in social networking site
So tia uploaded the pic to give the news that there plan failed
This is the main reason why mostly tia always take pics when she is in oberoi mansion to give information to her partner in crime without contacting that person directly
It was tia herself who had uploaded mallika and shivay pic why
To just bring more trouble and defame oberois
So chances and clues show it is tia who is the insider whoz helping the enemies
Not sure who is her partner gayatri or roop or shwetlana or all of them are together
