Ex-pop/ enemy ideas anyone?

With the new story progression and the escapee reagent I had an idea about an ex-pop that's a jaded / worn reagent that's been there for years like noakes but decided to not risk escaping out of fear of been caught , they could function as a passive enemy doing things such as spiking health items , knocking you over making you drop an item or lock a door on you mid chase anyways what's you guys' ideas ?
