i think its SJ... every single time Devyani was attacked he was there... he has an easy entry to the house... now he is trying to be friends with Devyani so that no one will doubt him... he is gathering support from people like priya and later from adi, uttara, vidya and when everyone will support him for marrying devyani, she wont have choice... by attacking her he is proving that he is caring, loving, and helpful... i cant vote for SJ becoz it says for refusing him but the attacks r happening before refusal...
