Hindi TV Serial - Pyaar Kii Ye Ek Kahaani - Haseena getting into a dangerous mode, bites and kills T

The serial has been moving a bit slowly for the past several weeks (the confrontation between Jay and Abhay has not happened except for some verbal dialogues). In addition, Chand has told Abhay to focus on Alina, since she seems to be the weak element of the werewolf family, and Abhay has decided to follow this. Alina also got a makeover from the others such as Piya and Misha, and looks much better with a new look. Abhay is now spending far more time with Alina, and Piya knows the reason, but she does get jealous from time to time. Jay of course does not like that Abhay is spending so much with Alina, and considers Alina to be totally useless in terms of helping the werewolf family beat the vampires.
The other major twist in the story is about the change in Haseena. Recently, there have been several cases of humans being attacked and killed, and the culprit seems to be a vampire, and after some detection, it is found that Haseena is doing this. Haseena explains to Abhay that she is getting an uncontrollable urge for human blood, and it is difficult to stop this. She even attacks Chand once. As a part of these attacks, she apparently attacks and kills T, which would mean that this would be the end of the road for T's character. Haseena also tells Abhay that the only thing that can save her is a serum which can be provided by Alina.
However, this is still not clear as to what is happening to T's character, since after her death, T calls Misha, who is shocked to hear the voice of T, who is presumed to be dead. So Misha goes off to T's house to determine the truth.
