Hindi TV Serial - Pyaar Kii Ye Ek Kahaani - The deaths of Panchi and Mythili in a single episode

For some time now, the serial had been dragging the story around a magic potion. The potion was supposed to give a huge number of new powers, and only Alina had the power to find the potion and to use it. Alina also had a special power that came into use once when she was being threatened by her own brother Jay, which caused injury marks on her own brother.
For the recent few weeks, the serial has descended into chaos. Everybody is hunting for the potion, with the werewolves, the vampires, Mythili, and others all looking for the potion inside a graveyard. At the same time, Arnab was also hunting for vampires with a group of people using instruments which apparently are able to detect a blood hunting vampire (Mythili) - one is not sure what such an instrument would be like and how it would be made.
At the same time, there is an impending romance between Kabir, where Kabir has fallen in love with Misha, but is not able to tell her. It is only when Mythili starts attacking the 2 sisters (Misha and Panchi) when she is sent off by Arnab with these 2 (when Arnab thinks that this is actually Piya), and then Kabir gets injured, is when Misha realizes how Kabir feels about her.
Things get even more complicated when Abhay is almost killed, and then the potion is the only thing that can save his life. To the horror of Chand and Haseena, they find out that the rest of the vampires were only around Abhay in order to try and get his spirit, since that would give them a lot of power. It is then that Piya and Alina come there with the potion and finally manage to save him; but the use of the potion turns him into a human and he is no longer a vampire. In the fight, Mythili is killed by the rest of the vampires, and Jay just manages to get out of there by claiming peace (but he is determined to hunt down and kill Abhay). At around the same time, Panchi also dies in hospital, never recovering from the injuries she suffered at the hands of Mythili.
It is now 3 months after these incident, and Abhay and Piya have moved to Mumbai; while Jay is wondering how to attack Abhay.
