Basic Trope: A character mentions their shared past to another to communicate a plan.
- Straight: Dracone has a gun to Bob's head as Bob talks to Alice over the phone. Bob mentions it's been a while since he called her Aunt Eva. Alice's Aunt Eva runs the local magic shop, and they've used her name multiple times to refer to plans involving smoke screen exits.
- Exaggerated: Bob never communicates a plan without referencing their shared past.
- Downplayed: ???
- Justified: Bob can't take a chance on his captor finding out about the plan.
- Inverted: ???
- Subverted: While being held captive, Bob talks to Alice about how it's been a while since he called her Aunt Eva...but her name has no significance with regard to plans; he was just talking.
- Double Subverted: ...However, then he mentions the phenomenal magic show she hosted a few weeks ago, which was to remind Alice of the tricks Aunt Eva taught her and give her ideas how to spring him.
- Parodied: ???
- Zig Zagged: ???
- Averted: ???
- Enforced:
- The author is a codebreaker and thinks this kind of indirect communication is cool.
- The author is using a Noodle Incident to make the unspoken plan less blatant.
- Lampshaded: ???
- Invoked: ???
- Exploited: ???
- Defied: Dracone, who's holding Bob captive, doesn't allow him to communicate with Alice at all.
- Discussed: ???
- Conversed: ???
