This stupid villain decided to attack in the middle of the day in the middle of the city. This stupid villain decided to attack in the middle of Lance’s science final. This stupid villain is making him rush through the streets, and he’s getting too close to the asphalt in his haste, and it’s making him a little anxious.
Lance is all for taking risks if it’s fun and not that life-threatening. This is just scary. He faces death way too much–he’s on his way there now–he doesn’t need to die because his web snapped and he fell, making himself into a squashed grape on the city street. That would just be dumb. He wants to at least die doing something important like saving people’s lives.
