WHO KILLED?????

Hi everyone,

KTH eventually ended with the reunion of kashish and sujal which was really nice of ekta.....but still i think she winded up last few episodes very quickly....many questions remained unanswered esp who was the killer of rishi? did akshat come back? what come of Dr.archita? etc what do u ppl think who really was the killer of rishi....also did mehak marry abeshek?
