Five days after Armageddon ignobly fizzled out before it really got started, Warlock will cautiously approach Aziraphale while he's cooking dinner. Eyes downcast, he will explain how he never read the letter Aziraphale left, how he tore it up and threw it in the fire. Aziraphale will tousle his hair and tell him not to worry about it. The letter was just to say goodbye and that they'd be back soon enough. Even if things didn't quite turn out the way they had thought they would what with the whole Antichrist mix up, here they all are together again, so it all worked out.

Three days after that Warlock will wake up screaming from a nightmare, calling out for his mum and dad. Crowley and Aziraphale will burst in the room, uncertain of what to do but entirely willing to forcibly relocate the Dowlings to the flat if necessary. Instead Warlock will leap out of bed and latch on to Crowley, sobbing and calling him mum. The following morning Warlock will be fully prepared to be embarrassed by his scene the night before, until he comes across Crowley drinking from a mug reading "World's Best Mom." From that point forward Crowley will be mum and Aziraphale will be dad. Some people will give a side-eye at a male-presenting mum, which Warlock and Crowley will deal with by making it clear their the weird ones for thinking it's weird.

The day before the start of autumn term the four of them will move to a house in South Downs. The new house will have a study for Aziraphale, a greenhouse for Crowley, a game room for Warlock and Sister Cat, and a big yard for all of them. Warlock will have a little trouble adjusting to his new school, but before too long he'll have his own group of friends he gets along with much better than anyone at his old school.

Despite his new friends, Warlock will remain close to the Them as well. Things will change and grow as they get older, but frequent visits between South Downs and Tadfield will ensure their friendships survive.

Sister Cat and Dog will become best friends. Frequently Dog will be found in South Downs or Sister Cat in Tadfield even without their people accompanying them. Their owners will choose not to question this, in the same way they will choose not to question the orange sash that looks suspiciously like the one Beelzebub wears that eventually joins Gabriel's grey scarf lining Sister Cat's bed.

When Warlock is fifteen he'll enter a rebellious phase. It will last two weeks. A rebellious phase is hard to maintain when your mum is egging you on the entire time.

As he grows Warlock will display a continuous knack for maths, and will eventually develop a love for sociology. These topics fall far outside the realm of what Aziraphale and Crowley are interested in; they like humans but not the analytical scientific study method of sociology and maths is, well, maths. As much as they would have liked Warlock to be interested in botany or astrology or literature or history, they will continue to be supportive of his pursuits, often to an embarrassing degree.

While Warlock is in his second year in university Aziraphale and Crowley will call him up to tell him they will be getting married that next summer. Warlock will dryly comment it's about time, and he'd been beginning to suspect the two of them of running off and eloping without telling him. Aziraphale will win the coin flip to have Warlock as his best man, and Adam will be good-naturedly amused about being second pick. Warlock will cuff him on the arm and say, "Story of your life, huh?"

Warlock will fall backwards into politics. It's not a subject he's interested in aside from the vague connection to sociology, but that's not why he'll choose to pursue it. He'll pursue it because he'll still remember being eleven and helpless against War and Famine and Pollution. He hadn't helped save the world back then, not really, but he'll refuse to spend the rest of his life helpless.

There will be various romantic relationships over the years. Warlock's heart will get broken a time or two, but more often it'll be him walking away, sometimes from relationships that seem very promising. He'll explain he's looking for love like what his parents have or nothing at all. Aziraphale and Crowley support this. Most other people think he's being sweet but naïve. While they're are busy rolling their eyes at his high standards, Warlock will find that perfect someone, and they will be more than worth the wait.

When they have kids, Warlock will be determined to never let his work get in the way of his family. It still will occasionally, but Warlock will always be there for them when they need him, and often even when they don't. At night he'll tuck his kids into bed and tell them one day they'll have the power to crush the world beneath their boot heel, but they mustn't do that, because the world is a beautiful place and all life deserves to be cherished.

When Warlock is 36 and Sister Cat is 25 – much older than any cat has any right to expect to be – she will pass away. Warlock will be grown enough by then to know it's not embarrassing in the least to throw himself on his mum's lap and sob with loss. Afterward his dad will make him a mug of hot cocoa piled with whipped cream, and the three of them will quietly share their fondest memories of her. And, in a few months, Warlock will make room in his heart for Brother Cat.

Because that is what Warlock does; he loves. Warlock will love and sometimes he'll lose, but he will always come back to love. He will wring every last bit out of every moment of life. He will live each day to the fullest, content in the knowledge he is loved unconditionally, irrevocably, eternally and knowing that he and his children and his grandchildren and all his descendants to the very bitter end will always have a guardian angel and demon looking over their shoulders.

But that's all yet to come. Today is Wednesday, four days after the Apocalypse that wasn't. It is a nice day. All the days since the world nearly ended but didn't have been nice. It's as if the Earth, knowing what could have happened, has decided to take a bit of a breather for a while.

Crowley, Aziraphale, Warlock, and Sister Cat are all in the Bentley riding toward Tadfield. They have plans with the Youngs that night for a belated family birthday dinner for Adam and Warlock. Arthur and Deidre are under the impression Adam and Warlock are cousins, and they never quite get around to questioning how that could be possible when neither of them are related to either Crowley or Aziraphale.

They have other plans for before dinner as well. Warlock and Sister Cat are meeting up with the Them, including Dog, to get a tour of all the best parts of Hogback Woods and Tadfield. Warlock has his BMX bike sitting on the bike rack attached the back of the Bentley. The bike rack has tartan straps. Aziraphale and Crowley will be spending some of that time visiting with Anathema and Newt in Jasmine cottage, but they plan to spend time with the children too.

Aziraphale is currently turned around in his seat talking to Warlock. Crowley is ostensibly sitting forward with his eyes on the road, but truthfully he's glancing at Warlock in the rear view mirror far more often than would be advisable in any car that wasn't more or less capable of driving itself when it needs to. Warlock's eyes are sparkling with excitement as he talks about getting to try out the tire swing. He gestures emphatically, but is mindful not to disturb Sister Cat curled up in his lap. There's a picnic basket on the seat beside him, a tartan blanket sticking out of the top. Stretched above them is a vast expanse of clear blue sky.

God smiles to Herself as She slides the last puzzle piece into the right space with a satisfying shunk.
