13 :)
(I have no idea what ask meme this may have come from, but I do know that it corresponds to the drabble I’ve had sitting in drafts for months of Doug switching Henry’s coffee to decaf.) It had been awhile since Henry's first visit to Doug's doomed universe, and since then they'd developed a pattern. They'd worked out exactly how the multiverse travel had happened, and Henry had fallen into a habit of visiting when he had the chance. Being a workaholic, it wasn’t often, but Doug appreciated every moment of it.
When he did finally end up in Doug’s universe, it was usually because he was so exhausted that he couldn’t keep working if he wanted to. Still, he was persistent and, despite being shaky and exhausted, he refused to sleep. He’d brought paperwork with him that he insisted he was going to finish, and Doug had been sent to the break room to retrieve coffee for the task.
Opening the container of coffee grounds, he paused. He had an idea. Though he was sure Henry would have to sleep sooner or later, sooner sounded like the healthier option. He may not have been able to keep his Henry safe, but the least he could do was keep this one from giving himself a heart attack. There had to be decaf around here somewhere...
