br "Don't let him throw up all over my baby, Sammy," Dean tossed back to Sam, who was folded into the backseat of the Impala, his year-old son spread out over his chest, playing with his father's shirt. The car was pulled over onto the shoulder of the highway, in the middle of nowhere, in the middle of the night because David – who had loved the car since he'd come to his father six months earlier – had suddenly started getting carsick two weeks ago, and the only thing that stopped him from sobbing and throwing up until he fell asleep was if he started out asleep. Days on the road, like today had been, had become a lot less enjoyable.
br "This," Sam said, holding the baby up as far as he could and letting David kick his feet around a little, "is your baby. i That /i is your car." Dean just rolled his eyes and reached towards the baby, who held out his arms and giggled, squealing.
br "No, you'll just keep him up," Sam said, pulling the baby back, David pouted.
br "Dee!"
br "No, not Dee, Daddy," Sam urged, "come on, Davie, Daddy."
br "He doesn't want Daddy, he wants Uncle Dean, who is fun," Dean corrected. "Because David is fun, and David does not want to go to sleep, unlike Daddy, who is about to start drooling all over Uncle Dean's upholstery. Get some sleep, man. I can tire him out."
br "Yeah?" Sam asked, looking hopeful – he was already half asleep by the time Dean reached over to take David, who was squirming wildly, out of his hands. Dean, not really able to resist at the best of times, kissed his brother on the forehead and then lightly on the lips before pulling David onto his lap. David, still giggling and drooling, reached out and put his hands on the wheel of the car – reaching out for the horn. This was not an activity of which Sam actually approved (as far as Dean could tell there were about six things that he was actually allowed to do near the baby), but David loved playing with the car, and if Sam weren't already fast asleep in the backseat – though Dean really had no clue how, he was literally folded in half, and the angle of his neck over the baby seat could not be comfortable – Dean would be letting the baby play with the horn. Besides, he figured it was never too soon to start instilling his baby's love of his other baby (and yeah, OK, he'd never tell Sam that that's how thought of David, but it was true, the kid was not just his nephew).
br Checking to make sure Sam was actually asleep, he leaned over and put his mouth next to Davie's ear and started making little beeping noises, and zooms and rumbling into the baby's neck, making him giggle louder. Oh, sure, he was only riling him up, but Dean wouldn't be tired for a while and Davie'd knock himself out in about twenty minutes, and then he could haul Sam's gigantic ass back to the passenger seat, buckle the snoring baby in, and drive until they found a motel in the morning. Besides, it was kind of fun – though he'd never tell Sam that.
