Guest-star continuity · HOTH-04
Reversible guest biography / acknowledged absence
Temporary performers are managed through exit routes that preserve continuing character canon or acknowledge the absence inside the story.
What this relationship type claims
reuses the mechanism of. A repeatable dramatic device recurs while surface content changes. Distinct from plot-mirror, which aligns a whole sequence of beats.
Read from the other side, the same record says supplies the mechanism for. There is one record here, not two. Chronology rule for this type: Source must predate target. Violation is a hard validation error.
Chronology
| Side | Work | Where | Year |

The earlier side
Matthew says he is an only child; “Twins” ends by revealing Andrew is adopted and Matthew knowingly preserves the twin fiction, leaving the earlier statement true.
The research describes this side rather than quoting it, so no exact script anchor is attached. The episode link above still resolves.
The later side
Rachel enters without immediate follow-up; Duncan’s absence is named and later minimally explained; Britta explicitly jokes about Abed’s girls disappearing, the deaf student receives a completed exit, and Rachel returns.
Described rather than quoted in the source research.
What changes on the way
Built-in reversible sibling story becomes later self-aware repair and absence management.
The changed element is part of the evidence rather than noise. A function can move to a different character, a power relation can reverse, several sources can combine, and the same mechanism can produce a different result.
How this record is graded
Scene reading An interpretation even when strongly supported.
The source research wrote this status as: “Strong production-method analogy; direct borrowing unproven”
