Yes Daadi tried to keep Pragya away and then everyone including Pragya try to not remind him of the past.
But at the same time, a lot of drama is going on in the house after Pragya is back.
So far, Varun drama, theft drama, pregnancy drama etc. etc.. These are very similar dramas to what has happened in Pragya's past with Abhi (Suresh/Champak drama- characterless blames, Pragya as a gold digger blame, Pragya pregnant stuff during the initial Tannu pregancy track etc.). So the parallels in the past do have a chance to trigger Abhi's past and cause him attacks.
I am saying this because Pragya witnessed that mere sight of Ravan burning caused Abhi to almost get some attacks. Also, Daadi noticed that just a picture of Abhi himself as groom caused him to get attack.
Yes it's a huge task to avoid past given anything can make him remember past. But then the team keeps on saying they don't want to remind Abhi of the past. However, what they are involved in right now does have so many parallels to the past (even us viewers find it all grand repeatsš).
So, are Daadi and Pragya not thinking about it?
Let's forget incidents.. but Abhi was hit on head by Nikhil recently. What if something happened to him? It's not the first time Abhi is hit by villains in his efforts to save Pragya. Why no one really worries about Abhi getting attacked again? Aren't these villains vs. Pragya fights put Abhi's health at risk more likely, given he is always driven to help Pragya?
Last but not the least, where is the doctor who should be treating Abhi? The specialist etc. Just eating gems tablets won't get his memory back na?š
