Hi all,
After watching today's episode (12/02/07 - Thanks Nomi), I'm 100% sure the baddie is Nachiket, simple reasons...
When I paused the episode when the baddie crosses out Saahil, the baddie has a light beard... look closely and you'll see!!
This rules out Tarun and many others, so somebody with a light beard and also the quietest out of the lot = Nattu!!!
Regards,
Rakhi
