The bugs had always struck Fresh as stupid; witless beings unable to tell the moon from a light-bulb, killing themselves in pursuit of home. Was this how the moths felt? The thought came unbidden.

---
or, Color realizes some very important facts about Fresh's diet, and the fact he's been unintentionally starving it.

Summary
What if Cross’s ‘secret admirer’ when he was in the Royal Guard was none other than Epic, a scientist attempting to establish communication with alternate universes?
Two parallel worlds were always destined to intersect. What leads to that? What happens when they do? What does it take for someone to completely change, and become someone new?
Or, before they were Dude and Bruh, how did they become Cross and Epic?
