Back here after ages. Im certain cons happened. I just wish it hadnt only because Imlie was shown to be a bit weak and tired. But Arpitas suggestion and Arylies conversation afterwards makes it pretty clear that it did. Especially considering that promo with Imlie being pregnant.
I think this is just another example of cons being super suggestive. Even in BALH2 fans kept wondering but in the end it had occured.
