two hypotheticals: pregnancy and twins?

Okay, two completely hypothetical questions that crossed my mind today:

1. a character can't enter the game pregnant, but can a character make a return/cameo being pregnant to tell current in-game characters? ex: a pack-born female who left falls pregnant, returns to tell her parents and goes back home.

2. if conjoined twins were to be born and survive for a few months, they could have two different players right?
