Mr.Bajaj and Anurag's death reason....

hey guys can anyone please tell me in DETAILS or send me the video of episode(s) where sam kills mr.bajaj and and prena kills anurag please i want to know why did they killed each other's hubby???? i have no idea please help me

kasak tired to kill tanisha's baby, sam and shravan found out and shravan accidently pushed kasak and she was pregnant since tanisha couldnt have baby so kasak was a surrogate mother....so, after then kasak gave a brith to a girl(i think) and she died cuz the doctor said that i can save only one person mother or baby and shravan told the baby, and bajaj thought that shravan killed kasak so he point gun on shravan and then anurag came and stoped bajaj, and them argument happened, then sam shot bajaj(this was all sam's plan cuz she didnt like prerna and anu togther so, she thought tht i will kill bajaj and prerna and anu will the enemy but something else happened) and prerna thought that anurag shot bajaj so she shot anurag....

Hope that helps 😛
