I'm new to this forum so I'm not sure whether or not this has been mentioned or not but I believe that Sayyam is rather young to marry Krishna if he really is the son of Suhani and Sambhav as the story only took a 14 year leap so surely he must also be 14years old. Whereas the other kids should be playing the role of almost 21 year olds.
I don't know whether Sayyam is actually that young but I'm assuming so since the leap was of 14years.
