Post-film, Alpha/Omega au where Alpha!Joe and Omega!Nicky have been together for the same 950 years, but due to the immortality Nicky cannot get pregnant, which they are fine with. However after the Merrick debacle Nicky starts getting odd symptoms-due to the experiments in the lab it somehow got reversed-and it takes Omega!Nile to connect the dots.
+100 for Alpha!Andy getting protective
+1000 for Joe talking poetically to their unborn child when they lie in bed
