Can someone update please?

Hello to everyone,

I have lost touch with Kyunki for a while now, trying to catch up...

Can anyone tell me

1. who raped kt? was it not mayank?

2. kt and eklavya got married - where has he gone?

3. what is happening between abhir and archita? how did they get married?

4. what went wrong between tanya and karan, i.e what led tanya spitting fire at nandini?

Thanks in advance
