Are the Kapoor's and Oberoi's really smart!

Firstly if anika is the lawfully wedded wife of shivay,how can shitia marriage hold any grounds.It has to be illegal right?
Secondly how did mrs kapoor and sevtlana caught hold of romi as soon as they realised that the chip is missing.

TV show Vamps=Superheroines+Genious+Most powerful+Rich(can buy anyone police, doctor, servant and all)+classy with good fashion sense(Tia is an exception)
So I hope u got ur answer!
