The more I watch Sleepy Hollow, the more it reminds me that they have used the idea of National Treasure as a blueprint in some way. You take historical figures from Americana and then give them a major twist in their backstory and  watch the awesomeness manifest itself and they are really going to town with the revelation that Benjamin Franklin had tried unsucessfully in creating his own Frankenstein Monster. So, the whole point of this episode is that Crane and Abbie want to take Benji's creation further in bringing to life it's own Soldier to battle the Headless Horseman. Abbie has dubbed thee.......Franklinstein's Monster!!! Hahahahahahaha. Awesome!
