Yup, I agree. Especially the way the promo was cut, she was looking like a grade A relationship-gone-wrong thriller ka psycho girlfriend villain lol. Sid should watch his step. Slowly distance himself from her. In fact, now Sid is cordial with Asim, who is also good friends with Sana, so maybe he can spend time with them both. Paras ke saath Mahira is always there, plus now Jariwala seems to be clinging to them (who Sana also doesn't like) so this wouldn't work. Plus, Aarti to hai hee.
I would be very careful now if I was Shukla.
