Sam is still a kid. He though, must be in this mid-late teens, he still doesn't know what can go around in this world, and how you need to be careful with 'strangers' etc. brainychild92 is right! He might begin to do things unknowingly, and Isha would be the one to stop him.
But what worries me is that, once his parents come in there might be trouble lurking around for the kids, in general. His mom especially is said to be in a negative role, and though his dad has a grey shade, he too would be negative in a way. EEKS! I just hope they dont join hands with Devki and Bhola. Uh oh.. I just hope the kids are in safe hands, and Chetna does things by how she would do, without coming under anyone's influences.
I am loving the story as of now.. Sam and the other are doing a great job! Love to see the diff. character developments taking place in everyone! Just hope, all the evil plans get foiled and the kids are in safe hands.. I pray.
