Bidaai on Star Plus - starting to reveal why Alekh is like this

Till now, Bidaai has focused on the condition of Sadhana, and then the romance between Ranveer and Ragini. It is only when the marriage has happened, that the story again focuses back on sadhana, and Alekh. Alekh's mom, Vasu is arrogant as usual, ready to scream at Sadhana if she sees anything happening to Alekh. Sadhana sheds a lot of tears everytime this happens, but is unable to say anything much to Vasu. Alekh however is not happy whenever this happened, and screams at Vasu whenever she is rude to Sadhana.
At the same time, there is an increased focus on trying to figure out what was it caused Alekh to turn this way, what was the events that caused his mind to become retarded. Slowly, you start to get some indications, with rose smell and the photo of his grandfather causing him to have violent reactions. Both Mamaji and Ranveer want to figure out what happened.
Further, Alekh's childhood friend, Shlok is also present in the Sharma house, and both in the Rajvansh house and in the Sharma house, there is an attempt to remember the happenings of the time when Dadaji died due to a heart attack and Alekh turned mad. As yet, there is no connection as to how roses came into the picture, and why Alekh turns violent whenever roses are there in the picture. Mamaji fights with Vasu over getting Shlok to help in the treatment of Alekh, since Vasu has assigned another doctor to help Alekh, and does not want Shlok to be in the picture.
