What Artemis and Apollo do on their spare time together

Sleep???

Apollo: Artemis, what are you doing up?
Artemis: Same question to you
Apollo: I always get up at this time
Artemis: It's 5 in the morning
Apollo: I'm aware
Artemis: Okay then...
Apollo: So answer the question
Artemis: My brain thinks sleep is for the weak
Apollo: That's all?
Artemis: Plus Athena and I may or may not have done a movie marathon of Harry Potter...
Apollo: Wow...
