Crashing through plate glass on to a concrete sidewalk doesn’t really hurt all that much, and is the kind of thing you can just shrug off with a ‘Phew!’ expression.
If you are a Hero Person, a good sneaky move is to hide somewhere, like up one tree in a huge forest of trees, and then wait until the Bad Person strolls by, and then drop on him. Of course, how you know he’s going to walk under your tree at the right time is… um, well, that’s not something we need to worry about right now. Moving on…
At night, streets are wet and shiny and look exciting. Always. Always, always, always.
Bad Persons have scars. Or, having a scar turns you into a Bad Person. We’re not sure which.
Bad Persons use Magic Machine Guns ™ that can spew out a gazillion bullets a second at a Hero Person, standing ten paces away, and miss.
The only known way to tie a Hero Person to a chair is with thick coils of fibrous rope that, quite frankly, a lazy kitten could escape from.
In most high-stress situations where a Bad Person is trying very hard to kill you and you face near-certain death, an appropriate response (and a good way to use your time) is to make droll, witty remarks.
The people who design and install ventilation shafts are driven, more than anything, to provide escape routes for Hero Persons. That’s why they have covers and grilles that can be removed by a little twiddling or a good shove, and are person-sized, cleanish and easy to crawl along. Also, ventilation shafts are routinely built into things, like prison cells, that you might think wouldn’t really need them.
