aditi... from whatever I have seen and have rarely missed a episode... and what I know of Taps as a character ... this is my take on this preganacy fiasco....
if she had concieved with Veer then in the first place she wudnt have had to fake a pregnancy ...as she wud already have been aware that she was pregnant ... but this conception took place later on when she lived in that hotel.... so by the time she realised she was really pregnant ...she was already in the btoon house with the fake pregnancy ... but luckily for her no one realised the time difference which is not much just a month or two here and there... so she smartly tagged Veer as the father...
and she never in her wildest dreams thought that someone else wud know her secret... thats the reason she keeps reiterating Veer ka bachcha ... as if she is trying to convince herself n anyone who has a doubt that its veer's...
If you noticed even when she met Rathod in the shopping mall ... he was taken aback as he did not know about her pregnancy... and she kept telling him Veer ka Bchcha hai... as though she was scared that he wud know its his ... but he being smart might have made enquries with the hospital where she did her check up and realised that the baby cud be his... since he was aware that she was not with Veer any more and also that he and Taps had been intimate...
as far as the CVs are concerned ... either they cud goof up and to support their fav couple may make it Veer's baby
OR they will be smart and having done a fab job of keeping the suspense & having built the story very well will sensibly turn it in to Rathod's baby....
