KT: No action no reaction

I thought that KT was tulsi's "parchaee".... I thought that she took after her and after tulsi KT is the next tulsi. In today's episode when she head that her baa has gotten shot brfore they found out it was Eku, KT didn't react as i expected her to. I thought that she would be the frst one to go slap bhoomi or yell at her or just go crazyor something but shse stood in theb ack and cried thats it. I thought that she owuld have the same reaction as Karan. WHY IS KT IN THE SHOW?????.....just for a love story or is something going to happen if something is then they should show signs........
