Gabriel was bored.
Anyone who knew Gabriel would be running away quickly despite the fact that if he was interested enough in you, you would never get away.
He'd been doing his Loki shtick for a good number of centuries by this point, hell it'd been thousands of years. Sure, the Bible said he'd been the one to give Mary the "good news" but that was one time and only because Dad asked. He'd promptly booked it out of the Middle East before any of his family caught up to him.
It was this kind of intervention that started off this story in the first place.
That being said, it was March of 1975 and he was currently hanging around England. It wasn't for any particular reason except for sightseeing. It'd been a while since he had 'hopped the pond' so to speak. To be honest, Gabriel felt a sort of urge to be there…something that was identified as soon as he appeared in London only to find traces of his Father whom had disappeared a long time previous.
Following the trail, he ended up at a manor in the countryside with his Father looking at it from a lush garden.
"Father?"
"It's been awhile Gabriel."
Gabriel felt the need to say that his Father was the one who'd truly disappeared despite the fact that he left Heaven first. His Father would have known where he was no matter where he went.
"Troubling times are coming."
"Mikey and Luci's big blowout?" Gabriel snarked however he quieted down instantly when He looked over.
"Sounds about right. Despite you leaving the Host, you still care about humans and punish those who should receive punishment. Hence, why I'm giving you a gift."
"A gift?"
God looked back at the manor before them.
"In here resides a devout woman and her 6 year old son. Her husband died not long after her firstborn was delivered. She's been praying for a miracle of sorts to improve the life of her family and she has one of the most pure souls that I have seen in a while. That's why I'm allowing both you and her a child."
Gabriel was awestruck. Surely he couldn't mean…
"Yes Gabriel. Despite what happened to the last Cambion, I am willing to allow another. Things will come to pass that I will not be able to interfere with, however I can only hope that this will help all involved."
"Thank you Father." And he truly was grateful. Cambions were nearly impossible thing in the universe. His Father was the only one who was able to create a true Cambion and the only one that had existed before was the brat he told Mary about all those years ago.
"He will be the best bet for the world with what is about to pass."
At least three decades later as he lay dying on the floor with an archangel blade piercing his heart while Lucifer stood above him, he thought back to the last time he had seen his Father.
He smiled.
