Miguel has many attributes being half spider, including some interesting similar to a spider, one of the more annoying ones is where he gets this instinct to sneak up on people, like a predator stalking its prey. He's tried resisting but its like an itch in his head and he has to scratch it. You were the unfortunate victim of this calling most of the time as you startled so easy, at first he was just scratching that instinctual itch, but then he started to enjoy the little squeaks and shouts you made. You've tried sticking bells to him, rigging small alarm systems in your lab, but he always works around them. Today you were convinced you found a way to catch him, it was maybe simple but you stuck bubble wrap all over the floor of your lab hoping for some peace. You sit at the table working on some web fluid variations when you get a chill up your spine and a voice in your ear, "Nice try but not good enough, pequeña presa"
