has anyone noticed how pretty much all the characters are an only child?

well except for hansel and gretel, dr ह्वेल, व्हेल (before his brother died and is now a zombie), james (before his twin brother died) and granny (before her brothers died) so basically the ones who arent या werent, their siblings are all dead with the exception of hansel and gretel. लोल anyways my point is that i've noticed that a large majority of the cast are implied to be an only child like regina, snow, emma, henry (both of them), belle, greg, archie, and rumple. i'm not ranting mind आप just something i've noticed lol
