Allies Need Conditions for Leaving, Too: Put a Companion’s Boundaries on a Relationship Card
A companion’s willingness to help does not mean accepting every cost. Use a relationship card to define the scope of cooperation, warnings, departure, and return. Distinguish proposals from actual boundary violations so leaving becomes an understandable character decision.
Start by deciding what would make them stop accompanying the protagonist
When a companion leaves should depend on both the boundaries they expressed beforehand and the facts they later learn. A character willing to help with an investigation but unwilling to involve their family may tolerate slow progress, disagreements, and even an unintentional oversight. But if they discover that the protagonist knew their boundary and still arranged for their family to participate without permission, they have grounds to leave. Their family does not have to suffer actual harm before they can withdraw.
The example below follows Xu Cheng as he helps his old friend Lin Zhou investigate a theater company’s account books. Xu Cheng knows how to organize records, and his younger sister works on costumes for the company. He wants to get to the bottom of the accounting problem but will not accept using his sister as a way into the investigation. All characters, events, and branches in this article are fictional teaching examples, not real user cases, tested results, or product features. The relationship card is a writing tool, not advice for conducting a real investigation.
The central conflict is this: the closer the investigation gets to an answer, the more likely the sister’s workplace connections are to be used. The reason for leaving must rest on an action. “Feeling disrespected” is an emotion; “the protagonist named the sister as a referrer and submitted a request without permission” is an event readers can verify.
Use a relationship card to define the scope of help
Fill out the card before writing the argument. Every entry should correspond to a scene and distinguish a proposal that has not been acted on from a boundary violation that has already occurred.
| Card field | Example for Xu Cheng |
|---|---|
| Reason for helping | Wants to find out why his old friend was accused of misappropriating funds and is willing to contribute his own time |
| Scope of cooperation | Check account books already obtained and accompany Lin Zhou when speaking with former colleagues who are willing to talk |
| Explicit exclusions | Do not ask his sister to obtain materials, use her identity to arrange meetings, or agree on her behalf that she will take part |
| Warning condition | Lin Zhou first proposes using the sister’s workplace connections to reach the person in charge, but has not booked a meeting or used her identity |
| Required correction | Abandon the proposal, continue with the existing account books, and show Xu Cheng the revised plan |
| Departure conditions | After a clear refusal, still submit a meeting request naming the sister as referrer or arrange her participation without permission; or Xu Cheng discovers that Lin Zhou previously concealed similar actions |
| Scope of withdrawal | Stop checking accounts and accompanying Lin Zhou; Lin Zhou may keep materials already received, but Xu Cheng will not finish the remaining work for him |
| Conditions for reopening discussion | Requests or arrangements involving the sister have actually been withdrawn, the plan for what follows does not depend on her, and Xu Cheng’s views are sought again |
| Limits on returning | Even if he returns, he will check only one specified document and will not yet resume accompanying Lin Zhou throughout the investigation |
To reuse the card, replace the character’s goals, exclusions, and observable evidence. “Do not endanger family” is too broad; “do not use a family member’s identity to arrange a meeting” lets you judge whether an action crosses the line. Also note who knows about the agreement, so the player does not hear a boundary that the protagonist has never heard.
Write the warning, discovery, and departure as three separate beats
In the first scene, Lin Zhou suggests that the sister might be able to take them to meet the person in charge. No meeting has been booked, no time slot reserved, and her name has not been used. Xu Cheng replies, “I can help you check the accounts. Keep her out of the plan.” This is only a proposal and has not yet triggered a departure condition. Xu Cheng gives a warning and suggests first checking the discrepancy between the dates in two records, giving them a clear next step in their work together.
In the second scene, the player chooses: abandon the idea of an introduction through the sister and spend time organizing old records, or name her as the referrer without permission and submit a meeting request to the person in charge. The first preserves their cooperation but may cost them the chance to approach that person that day. The second seeks a faster opportunity to meet, but crosses the boundary as soon as the request is submitted; neither approval nor the sister’s participation is required. The route that honors the agreement should also offer clues to investigate, rather than leaving them with nothing to do but wait.
In the third scene, the meeting request in the branch where the boundary was crossed is approved. Xu Cheng sees his sister’s name in the confirmation Lin Zhou forwards and asks, “Did you put her name down?” Once Lin Zhou admits it, Xu Cheng stops checking the accounts and leaves the volume he has not yet organized on the table. “Take the ones I’ve checked. I’m not doing the rest.” He leaves after receiving definite information, not the instant the player clicks an option.
If Lin Zhou hides the confirmation, Xu Cheng can continue accompanying him at this point because he does not yet know. The writer should record that the boundary has already been crossed and let the consequences follow when the character discovers it through a plausible channel. Delaying the departure requires a clear path by which the information reaches him. A character cannot know the player’s choice out of nowhere, and an undiscovered violation must not be treated as though it never happened.
How the investigation and the relationship continue after departure
Departure must change the terms of cooperation. Lin Zhou can still investigate, but loses timely help with checking the accounts. He can learn to interpret the records himself or ask a former colleague familiar with only some of the years to help. A replacement must not immediately duplicate everything Xu Cheng provided, or his departure amounts to swapping a character portrait.
The relationship does not have to reset to zero as well. Xu Cheng may still care about the outcome while refusing further requests to check accounts. A later greeting can coexist with an end to cooperation. If you want them to cut off contact entirely, add a reason—for example, Lin Zhou continues asking others to persuade the sister to participate after Xu Cheng leaves. Do not assume that “refusing to help” means “hating someone completely.”
Returning involves two questions: have the original arrangements been withdrawn, and is Xu Cheng willing to take on work again? Lin Zhou can present confirmation that the meeting has been canceled and show a revised plan, but that only opens a conversation. Xu Cheng may agree to check one document, or say they should get back in touch after everything is over. An apology expresses a stance; revising the arrangements is an action. Neither can make the decision to return for Xu Cheng.
Another option is to scale back cooperation: Xu Cheng still appears in other scenes but withdraws only from the investigation thread involving his sister. This suits a situation in which the protagonist has not broken the agreement and the two simply cannot agree on the scope of the next step. If an explicit promise has been deliberately broken, removing only one task requires an explanation of why Xu Cheng continues to trust the other person.
Use counterexamples to check whether the boundary holds
A common failure is announcing the boundary only when the companion leaves. Establish the agreement when the work is first divided so players can use it to judge their choices. Another failure is a fixed warning count: apologies work for the first three violations, then the companion suddenly leaves on the fourth. A count cannot replace the nature of the event. A first verbal proposal and a first unauthorized meeting request using the sister’s identity should not automatically receive the same response.
Check external events, too. If the person in charge approaches the sister independently, her involvement alone does not prove that Lin Zhou broke his agreement. Xu Cheng may still withdraw because the situation has become more than he can handle, but his dialogue should explain, “I can’t focus on the investigation right now,” rather than accuse the protagonist of something they never did. Departure can arise from a change in someone’s capacity and need not be a punishment.
Finally, ask scene by scene: When was the boundary made clear? When did a proposal become an actual action? How does the character know the boundary was crossed? What is lost when help stops? What step is still missing before cooperation can resume? If the answers amount only to a drop in affinity, one apology, and rejoining the party, return to the relationship card and add the actions. The card governs cause and effect; the character still has the right to refuse to return after conditions improve.
