I read a comment(sorry no idea by whom),if Sadhana didn't want to go back to the RV house,did she expect the brothers and sister to go?Doesn't she know the reason that they came out cos of her?And she has to speak up!I mean they must have decided to go back after much thought right(acc to the scene in the pre-cap on the terrace)and Sadhana as usuala would be looking at all of them instead of expressing her own views till the very last minute(I will take back my words if its something different)And Khamoshi ka kya matlab hua?She did once abt not talking to her sister during the rift track and even now based on her silence they must have expected her to go with them.After all Ragini pointed out that they both wanted that.Am i bashing her?
As for being illogical and unrealistic and dumb,Shlok's track paved the way followed by the rift track.So,I don't think its the first time in the history of Bidaai!
