Do you know what would be funny? Fatherinnit meets Dadbee after many years, right? Kind of awkward, the kids do a lot of the talking, Theo wants to leave to clear his head, and Toby also wishes to process what just happen, but he manages to ask Theo if he's gonna stay in the area... and Theo doesn't know, he just says they will be around.
And they don't see each other for a WHILE, the kids do, and that's how Toby and Theo get to know about each other again through them. They also win the titles of "uncle" there... Months pass and Theo gets his first job, some shady guys want him to kill a person who has been a problem for them for a while and they were willing to pay a good amount of money. Theo accepts, he plans to use the money to settle down in that cool spruce forest away from the main city.
The funny part? Toby is the person he needs to kill. Do we have angst here? Nah... Theo is actually curious about how Toby managed to piss off those assholes, and they end up having a little camping trip. Just the two of them, talking about the kids, crazy adventures they have.
But then Theo remembers his mission, he was gonna say "fuck it" and go back without doing anything... But Toby said, "We could just fake my death, you know?" And he said it in such a simple way that Theo couldn't avoid laughing.
They end up doing it, and Fatherinnit also gets more money because he told them "The fucker was a pain to kill, I think that makes me deserving of more." What were they gonna say? No? To THE Theseus!
They laugh and split the money, Theo asks what is Toby gonna do now? Dadbee is not sure, probably move, maybe going on a trip, until Theo asks... "Do you want to live with me?" It was an impulse, some old part of Theo's mind where he didn't have a filter to his words.
He was gonna take it back, but Toby was already excited and seeing him like that made Theo realize that he did want to live with him.
And that's how the idiots started to live together... At least my headcanon.
canon, i declare this canon!!! if you don't mind that is, i just- i really like this premise as well and i don't have any other ideas on how they first moved in with each other
