There's that. Oh, haha, in one of my modern AUs (which is a fix-it fic AU to someone else's modern AU, which I have fixed such that Katte DOESN'T DIE), I was writing a passage earlier today where Fritz is lamenting to Katte that, if only he had paid attention to all the things Dad was trying to teach him all these years, he might be able to come up with a plan that doesn't suck for keeping Dad from capturing him. Poor Fritz, damned if he does and damned if he doesn't.

In real life, I'm not sure how much going along with FW's upbringing would have taught bb!Fritz to come up with decent escape plans. It's a good question. But it was definitely not Fritz's own self-teaching priority, when he was desperately squeezing every spare moment he could sneak in on music, literature, French, and the arts.
