this could happen

i have thought over and over abt this story
n ofcourse its drivin me crazy
but the conclusion i have reached after watchin todayz epi is


arjun said to ganga rai "woh aarohi ko dard pauchana ki koshish kar raha tha"
"usne ek ladki ko isstamal karne ki koshish ki"

now here according to me comes that guy who gave arjun that jokers job
i think he's KS's brother or somewhat related to him
n accordin to AYAZ'S interview to TB he said his character is grey
n his track is with sur

so now that guy along with KS will try n take advantage of sur "usne ek ladki ko isstamal karne ki koshish ki"
n this will hurt arohi "woh aarohi ko dard pauchana ki koshish kar raha tha"

so arjun kills karan singh
