is the reason Cole calls Marrow "dad" and not Hamish, even tho (iirc) they were together when Cole was born, because Marrow was the one who gave birth to him?
Asking as a joke but also kind of serious
There is no mpreg in Ba Sing Se ;;;w;;;;;
Cole refuses to call Hamish dad because he's a little shit and threw all his frustrations at poor yeen dad #2.
