Arch enemy

Yet he went to break shivji mandir n 3000 years old haveli of naag vansh

There he was cursed aapko saanp ka shraap lagega barbaad ho jaayenge aap

Yesterday episode Andy was very discomfortable when Sumi was hell bent to throw bela out calling her ayiyaash n questioning her character Andy supported bela then 180 u turn n he became very discomfortable

He might know how to control naag naagin

Jisko curse hai wo savdhaan to hoga hi

Andy 25 years Sumi k saath possible he knew Sumi is naagin n hide the truth just to become rich

Greedy Andy

Regarding yuvi

Currently he is powerful with strong poison in his body he is well aware of his mom deeds plan n why she is doing

Raajdaar in her crime

Yuvi knows behir to yuvi being powerful knows too to control snakes

Sumi has blind trust on yuvi

Coz she thinks yuvi is like her

Yuvi is actually more smart than Sumi equivalent to maahir

Yuvi uses his smartness n observation in cheapness

Regarding letter the one who threw letter is not maahir coz Sumi is observing bela maahir n vish to trio can't talk to each other

Vikku use khud nai pata ki Sumi kyun karwa ri

Andy the greedy man is helping bela for naagmani

Yuvi too can help kyunki jo cheez asaani se mile why to shed blood

Sumi ko defeat karna is not easy but the one who is doing is from family n knows so well about sumi

And dokhe ki khaasiyat wo wahi se milta hai jahan se umeed na ho

Quite possible yuvi n Andy are in team

That's why Andy wanted yuvi to marry bela

And Andy apne faiyeda k liye apne bete ko use n barbaad nai kar sakta hai
