For:
a. Has a motive, for he continues to love Prachi
b. Has the support of the family, especially since he helped Prachi through all her tough times during the PA track - if he is indeed the killer, no one will believe Sukruti 😕Why SHOULD they?
c. Some ominous words from the past ring in my head; when Prachi once thought to herself, "Neev Jaisa Achcha Dost Aur Kahin Nahin Mil Sakta". Such words generally imply the opposite! lolz
Against:
a. He is just being too obvious😕
b. If he loves Prachi, why should he put both Mi and Chi in danger, unless he wants to take revenge, which seems slightly ridiculous
