Joshua Jones features the following tropes
- Disappeared Dad: Ravi's father is never seen, although his father (Ravi's grandfather) is a recurring character.
- Getting Crap Past the Radar: The word "Spanner" is often used as a vulgar insult in real life.
- Meaningful Name: Local rich jerk Mr Cashmore. Also Trojan the horse. Possibly Spanner too.
- Missing Mom: Fiona's mother is never seen or mentioned.
- Surrounded by Idiots: Mr Cashmore's attitude towards Spanner. Not that he's that bright himself.
