A/N: This happened thanks to a post from incorrectmsec on twitter and my conversations with Ellie so here you have it. (We're gonna pretend Henry still teaches at either georgetown or UVA for the purpose of this fic, doesn't matter which really)

Henry was puzzled. He couldn't quite make sense of the conversation he'd just overheard. Some of his youngest students- a class of freshmen who had been discussing him. He wasn't a proponent of eavesdropping, but he' been unable to avoid hearing the conversation.

"What about Dr. McCord?" the young girl whose name he was fairly sure was Katherine, had been giggling as Henry passed by.

"Definite BDE," replied another student confidently. The group then burst into raucous laughter, having no idea that Henry was nearby.

"He's a dad!" one of the others exclaimed. "Of, like, adults."

"BDE," said the second student decisively. There was more laughter, and Henry walked away unnoticed, but also unsure.

Now, he was home and he still had not figured out what the acronym could possibly stand for. He was sitting at his desk, a piece of paper laid flat on the surface before him and his pen in his hand. The letters BDE were written at the top, but the only possible solution he'd come up with to write beneath it read, "Best Dad Ever."

It didn't make very much sense, but they had mentioned that he was a dad, so he thought it was possible. He sighed, looking down at the page, and was still looking at it when the front door opened a few minutes later and Elizabeth stepped inside.

"Hey," she called to him.

"Hey," he answered, barely glancing up at her as he continued to focus on the paper before him. It took Elizabeth no time at all to notice that something was up with henry; he only responded that unenthusiastically to her when he was deeply focused on something. She slipped out of her shoes and headed over to his desk, pausing behind him with her hands resting on his shoulders as she peered down at the paper he was looking at. When she read the letters across the top, she froze.

"Uh, Henry, what is that?" she asked cautiously. She'd been informed recently by Daisy what those letters stood for, after twitter users had been utilizing them to describe Elizabeth herself.

"There were these kids in the library earlier and they were talking about some of the teachers, and this came up in reference to me," he said. Elizabeth couldn't help but laugh as she glanced down at the words her husband had written beneath, with a neat little bullet point in front of them. Henry whirled around to stare at her as she nearly doubled over with laughter.

"What?" he demanded. "What's so funny? Do you know what it means?"

"Well it doesn't mean best dad ever," Elizabeth wheezed. Henry rolled his eyes; he'd known it was a stretch.

"So you do know what it means?" he pressed, trying to sound forceful but failing because he found it impossible not to smile when Elizabeth was laughing like that.

"Yes," she managed through her laughter, leaning on the desk as she attempted to collect herself. "Daisy told me."

"So what is it?" Henry asked. Elizabeth bit her lip, leaned in, took Henry's pen, and jotted down the correct words, watching his face as she moved away. He read them and his eyes widened. He looked over at her incredulously.

"Are you serious?" he asked.

"Yes," she laughed. "That's what it means, Henry, I swear."

"But- but wait. Why was Daisy telling you this?" he asked, his voice slightly higher than normal. Elizabeth couldn't help but giggle at the sound.

"Because people on twitter said that I have it," she replied. Henry squeaked as he looked between his wife and the paper.

"What?" she asked, eyebrows raised. "You think I don't?"

"I- I don't-" Henry sighed, shaking his head as he leaned back. "I don't get it," he admitted wearily. Elizabeth laughed, and patted his shoulder as she walked by him.

"That's because you're not hip," she said, and Henry snorted.

"Neither is the word hip," he replied as he stood to follow her, deciding then and there to leave BDE in the past and to those who clearly understood it better than he ever would.
