Bhadrashal seems to have a KGB like spy agency, if he can know where Chaitanya's sasural lives. Or else, Chaitanya was being pretty idiotic when he told Chanakya that his wife & child would be safe there. Given how good Chanakya was about anticipating Bhadrashal's every move, it was surprising that he didn't rule that spot out.
Also, when Bhadrashal saw several soldiers being killed by one warrior, didn't it automatically strike him that it must be Chandragupta?The Mihika scene seemed to suggest that she was giving away Durdhara's love for CGM. If DN guesses Bhadrashal, it would be just too funny for Durdhara, since she'd either have to confess what she did, or quietly marry Bhadrashal. Her only hope then is that he gets killed.Incidentally, are they planning to end this serial once DN is dead, or will we see a return of Selukus? I want Selukus back, and CGM to marry Cornolio.
