OMG! never thought JR (Siddharth / Mr. Dubey) would drive me to post again in this forum, that too this soon.
But, somehow, I couldn't stop myself anymore. During the episode that was aired of March 5, 2016, the joker that was shown had the figure of a lady. The two most prominent features of his/her in that scene were his/her eyes and lips.
Even after trying very hard, I couldn't identify the eyes. But, the lips looked like they were Shabnam's (I know nobody wants her back). Those lips were fat, and both Bansi and Shabnam have fat lips.
Why Bansi now? Because the hand, which touched (almost) Sid and Roshni a few episode back, seemed like it was Kunal's. I am not sure whether Adhvik has left the show or if his character has come to an end (I feel his potential was under-used) and hence, I made such a presumption.
However, these are my views based only on the two-second screen-time of the joker's face, and not going by any logical deduction.
Also, the man (murderer) in the hoodie looked like Ganpat (oh! I wish his character remains positive as we can have great Sid-Ganpat interaction scenes in future, which could be hilarious).
