Maybe. It’s definitely against the law in Australia. Just checked America and it’s illegal in 49 states except Colorado. The adoptive/step siblings marriage I mean. Pretty sure blood relation incest is a big no-no on a wider range. Saying that the whole thing is mainly to stop parent/child marriages coz you know, gross

SURPRISE! INCEST! or maybe not, we shall see if they are blood bros or by marriage in the future.
