Toasty seems to understand the other responsibilities that come with the marriage, but she is also deluded that if the differences between Pashu and Malti are bridged then there would be no problem.
Toasty has forgotten that when she came to this house, the family took a vote, not because she was coming as an object, but because each member of the family would have a unique relationship with her and she had to win over all of them.
Even during her own ouster Toasty refused to come back on account of the fact that Tej did not come for her. She forgot that by refusing to return with Chedi and Pashu she insulted them. In real life, if the DIL refuses to return after her Jeth and Sasur (Jeth - Husband's elder brother; Sasur - the father of spouse) come to her house with folded hands, she would've forever closed the doors to her return.
Today I realized that Malti has not changed when they showed her dream sequence. She seemed to be thinking about only Pashu and herself. She has no concept of the extent of physical, emotional and mental trauma she has caused the other members of the family. Laughably, she expected Pashu to apologize to her for not understanding her.
Both Toasty and Malti have failed the litmus test of a Bahu in this track. They need to understand that unless Ved's scars are healed, unless Dadaji is able to walk again and Chedi's trust is won there can be no return for Malti. Malti has created her own problems, there can be no return for her unless the wounds she has given are healed. If Dadaji can never get up from the wheelchair, Malti can never return to the house.
