@Dreamz...see I just had a similar thought of Anita and Ahem working together, specially like an old b&w movie where a husband makes his wife think she is going crazy by changing her wardrobe to like a size smaller than her actual size. It was a suspense american movie. Anyways, i digress, I dont think its Anita and Ahem because the foot prints behind Ahem's sofa don't make any sense.
URshi still makes sense as the culprit because in the Ahem sofa scene there is no reason that Rashi came to that side of the sofa considering the entire family is on the other side where she should be helping with serving sweets and etc.
I think Ahem will commit her to a psych ward. I would like for him to help her, and have like a hero complex and want to save Gopi, but the psych ward helps him out a lot. He can get rid of her no questions asked by Kokila, Gopi will be taken care of at the mental institute and he will be free to remarry and give heir to the modi family.
Maybe this will be the impetus for Gopi leaving Modi bhavan, becoming educated amongst mentally ill individuals and then being released in a year's time when she is declared rehabilitated.
