Too many questions

Now that it's shown beyond doubt that Sumi is the master villain, there are too many questions

1. How did she marry Mr Andy saigal? And why?

2. She seemed sad n defeated whenever andy was with poulo... Was she pretending all along?

3. Why did she suddenly kill poulo? After all these years?

4. What is aadi's equation with her? Does he knows that his mother poulo is now dead?

5. Why was she so keen on getting Bela as her bahu , either she marries vikranth or yuvi or maahir?

( I think I know the answer to that..

Once she thought vikranth was dead/gone she needed naagmani some how n so decided to get Bela closer to family by marriage)

6. Why would she set up her own family's deaths with such an elaborate plan?

7. N the most important question- who is Andy saigal? How does he fit in her brilliant plan?

8. Are vikranth n maahir n yuvi brothers?

9. If yuvi is not dead n is coming back , who saved him? Because there's no way Sumi knew of vish plan to kill yuvi that night... Where was yuvi all this time?

10. Since yuvi can't die of snakebite as he is the son of a snake himself , same logic is applicable for maahir also , right?

11. Is maahir Sumi's son? If yes why would she want him dead?

12. Does maahir have any special powers?

13. Why didn't the gidds identify Sumi as a naagin?

14. Will vikranth n maahir team up in future to fight against Sumi?

What do you guys think?
