Klaus has some difficulty staying awake in the car
Even as Klaus grew older, the habit of falling asleep in the car stayed with him and this is why Klaus was having so much difficulty staying awake on this particular trip. This was the first vacation that Alexander and Klaus had taken in months, both having been way too busy with the expansion of Lucard Industries and cleaning up rogue vampires in the city.
Alexander chuckled to himself as Klaus jolted himself awake for the umpteenth time this trip. "What!," said Klaus as he realized Alexander was watching him, "Pay attention to the road!"
"You did it again, Klaus," Alexander replied, "And it was so cute too!"
Klaus could not help but blush.
