Three times a week, Dean leaps onto his bycicle and drives to the edge of his small hometown where, hidden and almost secluded, the beekeeper and his son live. While both of them are outside and communicating with the honey or whatever, Dean takes care of household chores and makes enough food to last them for a while. Ever since Cain's wife died, he had troubles taking care of his own household-- which Dean can sympathize with because his dad was the same, that's why a teenager like him is so good at it. Dean gets a small obolus for his troubles, which is why he had started in the first place, but Cain also teaches him how to play poker and some survival skills and Dean likes him well enough, so the money wouldn't be entirely necessary. He likes the company, and that's not just about Cain.
Getting paid is a good front, though, because like this, he can act as if he only did this because he wants to have enough money to buy the spare parts to restore the Impala he had found in Uncle Bobby's junk yard. Sure, the other kids in school wouldn't hassle him about his visits to the weird-ass and dangerous man and his even weirder son living in a witch house and are constantly talking about bees if he says it's about money. But that's not why he needs to put up a front, because fuck those idiots -- they were the exact same ones who had been bullying Castiel, Cain's son, once high school had started. They called him uncreative names like Cas-bee-el and honey mockingly while making kissy faces, tried to steal his bee backpack and laughed at him whenever he pulled out only a couple of slices of bread with honey on them for lunch. Castiel took it well enough, it seemed, because he remained stony-faced all throughout it, but when Dean once came to Cain's house after school and Castiel wasn't outside with his father and Dean could hear quiet sobs from his room after the kids at school at been particularly nasty to him that day (they apparently had found out that, despite his age, Castiel had gone trick or treating, and what is more, in a bee costume), Dean has had enough. After that, he beat up whoever dared to lay their hands on Cas and used every intimidation technique in the book to tell them to stay the fuck away. It worked.
Cas was huffy once he found out, telling Dean about how that hadn't been necessary and how he was not a damsel-in-distress, but he seems happy enough not having to sit alone during lunch anymore and to have Dean come to talk to him outside after the housework is done. He always talks about bees and honey and the beauty of nature, animatedly and with a big smile on his face. In the beginning, he used to shut down after a few moments, obviously suspecting that he was boring Dean or making himself seem even weirder, but after a while, he got that Dean wasn't trying to make fun of him, but that he was genuinely interested. (Also, the blush Castiel always gets when talking about something he really likes is adorable.)
At some point, Dean has gotten used to staying around after taking care of their household. He makes some more food so that when everyone is done with their jobs around the house and the honeycombs, they can sit together and eat dinner. Dean can't help his smiles whenever Castiel compliments his food and takes a second or even third serving, his cheeks as rosy as when talking about bees, and every now and then, Dean catches Cain smirking at him over the table. That's when he'll get just as flushed as Cas.
