Poison in Mahir

Yuvi has bitten mahir with his nidhok jaher..

And as there is no remedy for that poison Bela thought of healing him with Naagmani..

But once she brought naagmani,

Sumi has taken it from her.

So he was not healed with Naagmani.

Then how he is surviving??

Dis they explain it n i missed r is it a blooper??

Also it was shown that Mahir was given some slow poison r something like that so that he cant recollect his memory n so he became kiddo..

Oneday vish has replaced those medicines n Mahir ji is back for a glipmse..

Now sumi is not giving those medicines(as Bela is with him i think sumi r yuvi cant give), so mahirji should b back.. But he is still kiddo..

Jus asking.. I might have missed their explanation regarding these..

But jus wanna know
