(Omegaverse). Harry Potter and Briar Potter are the children of Regulus Black and James Potter. Briar and Harry are twins (now seventeen years old). James is an Alpha and Regulus is an Omega. Regulus has been on birth control for years, not wanting another child, but James really wants a baby, so Regulus thought they’d try again, seeing if anything worked. Now… Regulus is pregnant again (with twins AGAIN, but he’ll find that out later). He just found out, and is about to tell Harry and Briar.
