# RunLineAsync(LocalizedLine,LineCancellationToken)

Method in [OptionsPresenter](/api/csharp/yarn.unity/yarn.unity.optionspresenter.md)

## Summary

Called by a [DialogueRunner](/api/csharp/yarn.unity/yarn.unity.dialoguerunner.md) when a line needs to be presented, and stores the line as the 'last seen line' so that it can be shown when options appear.

```csharp
public override YarnTask RunLineAsync(LocalizedLine line, LineCancellationToken token)
```

## Remarks

This view does not display lines directly, but instead stores lines so that when options are run, the last line that ran before the options appeared can be shown.
