Grace showing him how humans hunt. But now he can't stop. Even when Rocky is tucked away, small and scared, asking Grace to stop. Telling him the game is over, pleading for him to stop. But Grace doesn't. He can't stop. Something about this.. it makes him feel alive. Something he so despret to have proof he's hanging onto. He needs to remember he's alive. He NEEDS to be alive. Because if he's not? He's dead. He's a ghost floating and haunting the stars like his crew mates.

But now there' a separate problem. Rocky is terrified of what Grace is going to do on Erid. Grace says he's sorry, says he's only doing it because he's starving, promises he doesn't really mean anything he does to scare him. But he won't stop. And while Eridians are pack hunters and are very successful, He doesn't truely want to loose his friend. He doesn't want Grace to get trampled to death because he freaked out a pack of Eridians.

Plus.. He's a little worried.. Rocky isn't the best hunter on the planet, but he's a very good one. And if Grace can terrorize him like this, catch him by sitting and watching for hours, slowly walking towards him with no where else to go? What if Grace didn't stop even after he's no longer starving? What if Grace decides tapping the xenonite barrier isn't enough. What if he decides that maybe hunting to completion is more fun? Perhaps killing prey is an acquired taste one develops.

Statistically, Rocky knows an entire planet agasint a singular alien would be an obvious win, but Grace told him about the mammoths. How people were able to take down beasts 6 times their size and weight just by stalking. The only good thing is Grace admitted that hunting while Rocky was sleeping was extremely boring and not fun at all. So at least that confirmed his worry about Grace targeting sleeping friends on the planet.

Their relationship is strained. Tense. Rocky tiptoes around trying not to activate Grace's chase response. Grace tries hard not to think about how fun it was to tackle Rockys ball before the alien screeched in a frequently that nearly busted his ear drums.
