In Star Plus's Mahabharat, Abhimanyu requests Yudhishthir to allow him to penetrate the chakravyuha. Draupadi panics on seeing the holy thread that she had tied to Abhimanyu for his safety. Uttara becomes unconscious. Draupadi becomes delighted on learning that Uttara has conceived. She instructs a soldier to bring Abhimanyu, along with him. Meanwhile, Drupad tries to break the chakravyuha, but Jayadrath stops him. Yudhishthir permits Abhimanyu to break the chakravyuha.

In It's upcoming episodes, Duryodhan provokes Karn to kill Arjun with his divyastra the same night and thus Kauravas attack Pandavas at night. Bheem then calls for Ghatitkach, his rakshas son, who creates havoc and destroys Kaurav army. Threatened by his might, Duryodhan asks Karn to kill Ghatotkach with the divyastra which he had saved for Arjun. Thus Karn strikes Ghatotkach and he while dying increases his size, causing further destruction. The next day, entrapped and provoked by Duryodhan and Ashwathama, Dronacharya goes on to slaughter Pandav army and also kills Drupad. It is then decided that Dronacharya needs to be tackled. Bheem kills an elephant named Ashwathama. All invoke Yudhishthir to say the Ardhasatya and Yudhishthir gets into a dilemma.
