So confused regarding todays episode

After watching todays episode I am so confused please help me guys answer the following questions if you can?

1) At the begining of the the soap it showed Robbie, Kasturi swimming to the side of the river or sea and Kasturi was saying to Ronak 'open your eyes Ronak' Robbie was watching whilste laying down on a rock. Towards the end it showed that Ronak was not there? why?

2) How can someone possibly not breath for so long under water.It showed that the family members went home crying and Ronak mum blaming Kasturi mum whilste at the sametime they were still fighting for their lives?

3) Did Kasturi go to swimming lessons before mariage I always thought she was from a middle class family and her family were not even happy taking a job, then how did she manage to swim?

4) Did Robbie really push Ronak down the cliff? If he did he would never ever be forgiven evil!! 😡

5) Why wasn't Vikas worrying so much about his brother Ronak if he did he would have gone and look for him not sitting home with Tanu?

6) OMG the rescue team make me laugh the are so slow.

7) When Kasturi brother forgot his name, slapped his mum was it all planned?

8) Why has Tanu married Vikas when she doesn't love him?

9) Where can Ronak go when their were alltogether?

10) How did Kasturi manage to stay under water for so long. She sure must be some superwomen 😆

I think thats about it please just answer what youcan because I am so confused 😕. Thanks in advance guys. 😉

Dont know if you had noticed but things were going fast in todays episode they showed a liitle bit of Vikas, then the swimming then speedy recovery of Ronak whilste Kasturi still in bed, Kasturi chachee arguing with her in - laws family regarding Kasturi whilste Kasturi still swimming.

yeah i am also 😕 lekin kia kare yaar thats a K serial so dont expect any logic just switch off you're brain while watching 😆 😊

😆
wat is happening
i also think ka has taken swimming classes or ro has taught her when he pushed her in bath tub 😆

the scene in the water was the hilarious scenario i have ever seen.... from the top they showed us a lake but when Ka, Ra and Ro were in water it seems like its a pool and they are just making "goooooood goooood goooooooood" noise.....me and my bro were lauging out loud......and they actually showed the scene for like two days.....hahahahhhaaha....wat a treat from Ekta for Halloween.... 😆 😆 😆

my question is if kasturi know how to swim then why she did not jump first to save raonak life,why she was begging to robbie to save raonak life.
