Sharada I don't think they would've shown fake pregnancy. That was mostly the fans speculating the worst. They would've stretched the EshGu scenes for sure, showing as if Raghav still had some residual feelings/weakness for E, but I feel SS likes to linger on the third angle's romantic aspect more than the pregnancy drama.
I don't know Ru - the only way they could stretch this track was with Raghav sticking up with Esha and that would have happened only if there was a fake pregnancy track. Jo bhi ho - I am so glad the creatives have enough time to tie up the ends and not indulge in these stupid ex ka triangles.
