Shera is not the issue. Its actually a change from the usual.
The issue is the one sided dream sequences. Once or twice was OK. Now it is just becoming a forcefully injected medicine.. They're making Shera look like a comedy piece with those..
Hope there is not much of those in the upcoming epis.
The same comic relief can be given with Shera and Kalyani's actual interactions while they are solving the mystery.
Maybe after Shera saves her from the bonfire, Kallu can start having doubts that he could be Malhar undercover.
Or some subtle mannerism of Shera should seem similar to Malhar's for her get that doubt.
Right now she's not even having an inkling of it. That's why they are not able to show any feelings from her side.
