My mistake, the calculations for which trait they receive occurs immediately after the potion event choice, not before the sex scene. After the potion event the only way to add the trait is to make an edit to add the trait. The trait determines which text is used in the final event. Adding traits is not as intuitive as it would appear. There are a couple approaches to this as explained in this thread: https://itch.io/t/1675291/editing-save-and-mc-questions I recommend the approach in this post (https://itch.io/post/4753014) as the simplest approach.
