You can also tell about such features by having a walk-on character with a deformity or amputation. I have met at least four people missing one or more fingers, or with a half finger. Check out this link of disabled politicians (in the US, but also elsewhere): [https://en.wikipedia.org/wiki/List\_of\_physically\_disabled\_politicians#United\_States](https://en.wikipedia.org/wiki/List_of_physically_disabled_politicians#United_States) So you can have a bartender, delivery guy, messenger, store clerk, etc missing a finger, and your MC observes that: > Joe thought the worker was holding the hammer oddly, then realized he only had six fingers: The inner thumb was amputated near the bottom knuckle, and he had a weaker grip on it. _Probably a work accident,_ he thought. It wasn't the first person he'd seen that lost a finger or three to a circular saw. This kind of surprise or shock or 'resolved confusion' is related to conflict, or internal conflict, a puzzle to solve for an observant character. It lets you impart information, show him to be observant and a problem solver, even though the 'problem' has nothing to do with the plot; it is a character trait. Similar to humor, it can show a character thinks out of the box, is not relentlessly serious, etc. That might not impact directly on the plot, but it can help readers relate better to the character.
