This snippet is tricky, so here are some suggestions on how to approach it.
Perceiving emotion: Imagine how your secondary character is feeling and how they are physically expressing that emotion.
Environmental detail: Choose an environmental detail.
Connecting environment and emotion: Link the emotion to the environmental detail. In the snippet, Ort sees his mum crying in the door handles. This link doesn’t have to be as literal as a mirror. Look at the examples for other ideas.
Snap back to logistics: Finally, you can button the whole scene with an understated logistical observation.
You might find this snippet easier if your narrator is avoiding looking at the other character.
