Markat cave's lady (hybrid creature) and Singhania Mansion's imprisoned lady are different creatures! I wanted them to be different. Otherwise, it wouldn't have made any sense! It's not possible for fake Markat to stay in two different places at the same time! These two ladies/creatures merge together and become one. So, I think Markat cave's hybrid creature probably killed Monil when Bani went to help the imprisoned lady. What do you think?
