They're fighting. They don't want to be fighting but they are. Cyrus wants to leave Star Corp to explore the stars, just the two of them. Juniper wants to stay, she likes the stability and she doesn't want to leave her younger sibling; despite Aspen telling her they'd be fine. So they're at a crossroads. Unfortunately for them, they still have to do their job and they just got paired together for a long, boring cargo transportation mission. 

Cyrus is an adventurous spirit, always moving from place to place with no real home in sight. Star Corp is the longest he's stayed in one place and he's getting antsy. He ran away from home and never stopped running ever since.

Juniper likes staying in one place. While she loves traveling, there's nothing better then having a permanent place to come back to after a long days work. She also likes being close to Aspen, despite getting the help they need and being a fully independent adult, she still worries.

The space organization the two work for. They go on many different types of jobs such as delivery and transport, rescue missions, and sometimes act as the occasional taxi for anyone rich enough to afford one.
