He has spent countless hours, every day, for months, with his nose in this Lego Star Wars Encyclopedia. Without hesitating, he can tell you what episode every figure is from, what year Lego first produced each set, what figures come with each set, and what the current price of all available sets are on Amazon (and how much that compares to the Lego Store and Target). The other day, I asked him to explain to Scott who the Separatists were. We are studying the Pilgrims in history. Kaden got a twinkle in his eye and proceeded to explain who the Separatists were, just not the ones I had in mind. At least he's able to focus his attention!
