Sunidhi and Kashi - send them away

Why doesn't anyone and by anyone I mean Pratibha or Pushpa put 2 and 2 together

- Sunidhi fed Namrata bhang on holi - she was the one that brought it and served it to Namrata.

- Sunidhi's kid ate bhaang - how did that happen?

- Prathiba caught Sunidhi counting cash - now she's heard there was only 11 rupees and not 11000 in the envelopes

- Sunidhi fed Pratibha coffee - after which she fell asleep and now jewerly is missing

How stupid is Pratibha? More so Puspha chachi's character is so odd - she was so sharp before but now its like she's put her brain on silent mode or something...

I don't get Pushpa Chachi's motive - she wanted to come back to Agarwal house just to host Namrata's wedding? Why coudln't they just rent a house and host the wedding from there?

Pushpa chachi knows Kashi and company don't like her and want to make her miserable (attempt to murder by smoking her room with incense or whatever Pushpa is allergic too) - what makes Pushpa think that Kashi will listen to her plea and cease fire for Namrata's wedding?

What is wrong with everyone?!! Why do they show Pratibha as so stupid and why is Sunidhi getting so much screen space?!!
