Summary
Getting your brain beamed temporarily into an Eridian body is really weird on the senses. On the plus side, though: there's now so much more of Erid to explore!

Summary
“Oh my god, Rocky.” I want to cover my face with my hands, but I’m not about to let go of him. “You’re insatiable.”
“I’m insatiable?” He looms a little closer over my face, forcibly bringing himself back into my field of vision. The bright holodeck lights catch in the sweaty sheen of my skin. “I don’t feel arousal. I am in it for the love of the game.”
Or: Look, if the Eridian scientists want you to test out a technology that lets you and your bestie kinda sorta touch each other for real, are you even a proper scientist if you don't consider how it could be used for sex?

Petulantly, Rocky says, “Grace sound stupid. Like child.”
“I’m just talking how you talk, buddy.”
“Yes. This is because I talk like child, to speak to stupid human.”
“Well, you don’t have to do that,” I say without thinking.
“♪♫♩as this♪ when, underst♪♪♫d ♪me, question?” Rocky says.

I'm Ryland Grace - AMA by sly_as_an_alpaca

Summary
What the title says. About 11 years ago (from my perspective; relativity is weird) I was launched into space onboard the Hail Mary to figure out a solution to the Astrophage problem. Now I live on an alien planet I call Erid, in the 40-Eridani system. Yes, I’m actually Ryland Grace. Ask me anything.
Also, can someone please tell me if Eva Stratt is alive? And ideally send me a video of you punching her in the face? Guess that’s a long shot, but it can’t hurt to ask.

Grace and Rocky figure out how to connect to Earth's internet from Erid. They may not have thought this through.

Summary
“Grace ever make love with other humans on Earth, question?” Rocky asks one morning when they’re just finishing up a modest breakfast in the Hail Mary dormitory.
Ryland nearly spits out his mouthful of pb&j but valiantly manages to swallow. “Why are you asking me this right now, dude?” he asks, voice still thick with peanut butter stuck to the roof of his mouth. “No lead-in or anything, jeepers creepers.”
