Prompts:

1. Killer almost dies when a mission went wrong. Nightmare gets worried when Killer doesn't wake up so tries to search in his mind to find the cause with Killer. Minds are weird freaky places depending on the personality.

2. Nightmare is free from the curse, but after being such a manipulative jerk he shut himself away from everyone, and Killer. Killer gets worried and tries to help him understand he's not mad at him.

3. Fantasy AU! Nightmare is a witch and Killer is his creation made to obey him. What happens when Killer slowly gets emotions?

4. Your diddly darn own thing.
