In the spirit of forgotten character traits: Jake English and machines.
Jake and Grandpa Harley are different iterations of the same base person. Grandpa Harley was a polymath. He was an inventor. He was the one to build Jade’s dreambot. With the amount of tech Jade grew up with, it’s quite difficult to deny that Grandpa Harley knew his machines.
Jake does too. When we think of “robots” and “alpha kids” Dirk is likely the first thought to come to mind, seeing as he built himself two different rapping compatriots. But while Dirk built the brobot, he transported it to Jake in pieces no larger than what would fit in an average microwave. It’s easy to forget that Jake still assembled a robot from pre-made parts.
Years later, he assembled a robot bunny for his penpal John, and while he had Jade and Dirk’s knowledge arguably at his disposal, it’s unlikely that either of them spared him much time and assistance. After assembling the brobot with help, Jake would have assembled Liv Tyler much more autonomously.
Jake also loves firearms. While his marksmanship is up for debate, knowing the assembly and care of a gun is similar procedural knowledge to understanding the parts and assembly of a robot. These are the sorts of skills Jake has. He might have the emotional range of a teaspoon and might miss social cues that are doing their damnedest to beat him about the head and torso, but he isn’t stupid. His intelligence is all practical knowledge.
Jake is resourceful. If he was a complete numbskull, he would have been dead a week after grandma Jade.
Much as he seems dumb as a post, I’d like to give Jake a little credit.
