How did Pammi change?

I hadnt seen ghsp from d beginning.now since i'm writing its season2 ff i'm researching on it.2day nly i came 2 know that Dev had a sis named Kamya.saw an epi where Dev's mom Pammi was there.Pammi was guilty 4 cheating on geet.se says 4 her Maan n Dev r alike.She even says tt maan luvs them a lot.she tries 2 clear dev's misunderstandings abt Maan.I saw Pammi only when she re-entered d show.But that time se was completely -ve,even tried 2 kill Maan.Pammi was so simple in d initial episdes.how cum she is so fashionable n colourful in her re-entry?How did she turn -ve like this?

It was really surprising...okey keep things apart we can say a person's mind can change means we can accept Pammi turning good to evil for Maan.But her outlook.how suddenly she changed from likely uneducated woman to such mod.Started to drive car...using pistol where once she was much afraid of NT a woman like her .Suddenly she started to challenge a powerful man like Maan...strange......
