It's because Lucy asks for what she desires that Cas began to clue into her as a person. They're closer to each other for it. More bourbon? No problem. Someone might have to remind him to take cash to the places he visited later. Snuggles under the blanket is something he's starting to see an appreciation for as it brings them closer.

Jack talked about her non-stop when she wasn't around.

What matters is the two of them find some way to keep the peace now. Sam used to get fed up with their antics. Dean's grumble now is nothing to fuss over. Ruby helps him see a future between hunting and something remotely domestic down in the bunker. He scoofs, but it's a genuine smile at Dean's chest puffed out. "You did good. It's honestly a little scary how quickly you pulled this together." Dean can volunteer the information on where it all came from or not. His brother can add whatever else he likes as long as Santa turns off at night. "You went all out on the food, too." Which is Dean's opportunity to go over that. In fact, he can't help but smile at some of the things Dean made at Thanksgiving. His brother was amazing with food.
