Alekh can lose Sadhna one of three ways-either he forgets her as part of his recovery track, he literally loses her because she has been thrown out of the house, or he recovers fully, changes into a fully functional healthy man in the next 3 weeks, and sees her as a wife and not a dost.
We are all hoping for the recovery to normal track, without some stupid Dulhann style forgetting her as his wife track. One way or the other, a kid is not happening in the next 3-4 weeks, the most time the SBS can seriously give spoilers for.
They havent even had a normal relationship as man and wife, and im basing the fact that the SBS prediction can be for the next 3-4 weeks, not the next 3-4 months. I do think sadhna is being framed in the upcoming episodes, and we all know Vasu in a nutcase when it comes to anger. She is capable of anything, even throwing Sadhna out, or making her leave or something like that.
