# Shadow Lines In Yarn Spinner Scripts, **shadow lines** let you reuse the same line in multiple places, without having to create duplicate copies. {% hint style="info" %} Shadow lines are copies of other lines, but don’t create a duplicate entry in the string table. This can be useful if you want to re-use an existing line in more than one place, which can be important when each line has in-game assets like voice-over recording. {% endhint %} Shadow lines are marked using the `#shadow:` hashtag. When you use the `#shadow:` tag, you specify the line ID of another line, which is called the source line. The source line must have an explicit `#line:` hashtag to identify it. Here’s a simple example of using shadow lines: ``` title: Tavern --- Ava: Hello, barkeep! Guy: Hi there, how can I help? Ava: I should go. #line:departure === title: Kitchen --- Ava: Greetings, chef! Guy: What are you doing back here? Ava: I should go. #shadow:departure === ``` The script contains six lines, but only 5 string table entries will be created, because the line *“I should go”* is shadowed. Shadow lines are required to have the same text in the Yarn script as their source line, but are allowed to have different hashtags (in addition to the `#shadow:` and `#line:` hashtags). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
