Maybe they want to reload Season 1. But I think it's not a very good idea! Season 1 never got much TRP. But who knows what the H they are thinking? I feel Vidyut's entry is what brings with it the big twist and the change in the story.
There is more to this Kid story, we will only find out in the next 2-3 weeks. Patience is the key. Almost all the cast have said this in outtakes including the leads. So I guess we just have to be patient.
The timelines in shows are ALL messed up. Juhi disappeared 5 years ago, Kid is 5, and Avni and Neil got married 1 year ago. In 4 months, 1 year has gone by? So dont go on the timeline much. But I also agree the accident would have been difficult to withstand for pregnancy. But in the initial stages this may not have been an issue. It's also possible she got pregnant not long after the accident. We will only know the truth once the whole story comes out.
