As it turns out, Rory Kinnear's long-winded, melodramatic speeches in Penny Dreadful are how the character was always supposed to be played. But if you're wondering who this French family is who taught the big guy to ramble like some lecturer at the Sorbonne University, wonder no more: It was the blind man's own family. In a plot development very convenient for the instruction of self-loathing abominations born out of scientific hubris, a Turkish girl comes to live with the old guy and his children. Large Frank squats in their shed for months, peeking into the cottage as they teach the girl to read and speak in French, and then completes his homeschooling with some books he finds by pure chance. He betters himself on his own, all the while secretly working hard to help this poor family in disgrace.
Now, this isn't acknowledged in so many words, but the monster is a goddamn genius. Just a few months after learning that speech is a thing, he's already speaking with verve and aplomb (and probably even using words like "verve" and "aplomb"). His first book wasn't a reading primer -- it was John Milton's freakin' Paradise Lost, and he understood it well enough to find Satan relatable. Who knows what he could have achieved had he applied himself to science like his creator, instead of moping around and wallowing in his own misery like an 8-foot-tall, undead emo. Instead of harassing Frankenstein for a girlfriend, he could have eventually built one himself. Of course, that'd have made him an even more pathetic creature -- an MGTOW (Monster Going Their Own Way).
