Gabriel/Beelzebub/Lucifer - Exile (Good Omens / Lucifer Crossover)

Thank you very much to Laura Schiller for the suggestion of Lucifer's motivation in the middle part! PLOT: At the Airfield Lucifer sees Gabriel and Beelzebub together and Adam's rejection stirs up old wounds. Michael threw her twin brother out of Heaven, Beelzebub fell and Gabriel stood by. Gabriel remembers Beelzebub's betrayal and Fall when they followed Lucifer during the Rebellion. They were partners once, now they are on opposite sides but still end up in an on-off-relationship every few centuries. During Aziraphale's planned execution he is convinced that the physical bond and love between Aziraphale and Crowley is what made the Angel immune to Hellfire and is painfully reminded of his own bitter love for Beelzebub. (He is not exactly right because they are not in a relationship, yet, but partially right because they swapped bodies, not exactly parts of their souls/true forms). Gabriel is jealous of his brother for giving Beelzebub a better life with a high position. The creation of Adam was without shared love between the rulers of Hell and when Adam rejects Lucifer, he feels torn apart. Not only is his son rejecting his purpose, but he also Beelzebub leaves. Adam was the reason they even maintained a business relationship and with the world restarted by the ex-antichrist, Beelzebub has new goals. Lucifer is so disturbed by the stopped plan, that he doesn't even see the matchbox as the sign that Gabriel and Beelzebub are meeting in pubs all over Earth. When he realizes that they are back together, the two exiled leaders are already on their way to their new home at Alpha Centauri. Beelzebub is a bit bittersweet, remembering all the time they lost by previous breakups, but in the end they are happy with what they share with Gabriel now, away from Heaven and Hell.
