“You all right, Professor?”

“I’m fine. You just startled me, that’s all.”

“Maybe asking about my Mom was a bad idea.”

“Don’t get me wrong, Shinji. We all admired your mother dearly. She was just—oh, my, how do I put this nicely—a very unique woman.”

“I’ll say. You’re the fifth person I’ve sent into coughing fits just by bringing her up.”

“We’ll explain it to you when you’re older.”

“I’m fourteen already.”

“It really isn’t—oh, all right. That’s what she would have wanted, I suppose. Come here.”

“Why are you whispering—AUGH! NO!”

“I did warn you.”

Unnecessarily Long and Tiresome Authoress’ Notes:
Originally, this was going to be a joke on Yui’s sado-masochist tendancies (a running gag in Shinji’s Alternate Universes), but I think the punchline works better if you don’t know what was being whispered to poor, traumatized Shinji.
