Summary
"I'll keep you updated. In the meantime, go back to sleep. When you need to worry, I'll tell you."
"Heh." Ryland ran his hand down his face. "It's terrible you know that it actually makes me feel better. What would I do without you?"
"Explode at a colleague at a conference and get expelled from academia and become a middle school teacher." Eva said, promptly.
"Wow, you've thought about that way too hard." Ryland laughed. "Middle schoolers might not vape in class, though. Maybe I should switch."
"Let's not joke."

Summary
The Hail Mary has been shot out into the depths of the infinite void of space to search for an answer that may not even be there. Aboard, the three crew members lay in stasis as the ship hurtles like an arrow towards a distant star, with no hope of return, but a desperate hope to make things right.
At home, two brothers are left in sudden and violent grief. A woman grapples with whether or not she made the right decision. The world strains and suffers under the weight of the coming Fimbulwinter.
And then one of the beetles returns.
Thirteen years early.

Summary
I had this little thought that Grace made himself a bracelet while on The Hail Mary and Rocky asked him what it was. Cue this silly oneshot.
༻✧༺
“A bracelet that is made of friendship?”“No,” Grace chuckled. “It’s usually made out of string.”
Rocky tilted his carapace to the side in curiosity. “Why, question?”
Grace shrugged. “It’s fun.”
Rocky was quiet for a moment. Then, he rolled closer until he was right next to Grace. “How do I obtain bracelet of friendship, question?”
