As much as Shivvay loathes the idea that he is connected to Annika (aka Mr. Darcy loathed that he was immensely obsessed with Ms. Lizzy) it is HE who cannot stay away from HER not the other way around.
Annika was hurt by the what he said and did today but she was not as affected by him
Shivvay was almost being torn apart and falling to pieces and that was evident by the way he held held himself together
If... and that is a BIG IF the media does hound and slander Annika he will step up and force a marriage. Of Course he is too proud to admit HER reputation matters so he will say it needs to be done to save HIS family's reputation.
There is a possibility of him announcing that she is the future daughter-in-law to shut people up at which point I do not think Annika would be able to refute that statement. I mean this is ,like I said, not the Victorian Age and spending a night at her place with Sahil and Bua there is not something people would make a big deal about but we all know the media when it comes to celebrities - they are ruthless and blood thirsty
