coming to topic shamsher tried thrice to kill rk.result unsuccessful.balraj tried to kill rk twice or thrice on same day once on bridge and by grinte .but unsuccessful.now sultan who wants to interfere in rishbala's life by taking rights to interfere in their life.what he knows only to kill if anything wrong happens.so if he see rk and madhu's tom and jerry fight [every now and then happens with rishbala],he thinks something wrong he won't ask or inform madhu but try to end rk's life.end result is break-up of friendship between sultan and madhu and madhu coming more close to rk.at that time rk should leave his little ego from his big size ego for madhu.
