* Characters in a fictional story: If you're talking about characters from a book, TV show, movie, or other fictional work, you'll need to provide the source material or more context for me to tell you when they might kiss.
* Real people: If you're talking about real people named Ash and Dawn, it's not something I can predict.
* A metaphor: If you're using "Ash" and "Dawn" as symbols or metaphors, you'll need to explain what they represent so I can understand your question.
Please provide more context so I can help you!
