i think when she cry sajjan feels guilt on that it was his dission to gave samar resposibilty to menka...and when sajjan give guns to their son pratgya didnt say a word against that action but krishna thinks sensible now...pratgya notice that and also dadi agrees with him soo as sajan and shaktiya too...pooor kid samar scared from dog becoz of menka ... menka se zida mujhey buri menka ki maa lagti hai ada time serial main uss ne lay lia...
