Rocky says that he is 291 years old. He also says that the average Eridian lifespan is 689. He's roughly 42.24% through his life. If we say that this is equal to the average human lifespan (I'm saying 80y bc I'm lazy) and that he's 42.24% of the way through 80 years; Rocky developmentally is basically some 33 year old who has just spent about 6.97% (5.5 human years) of his life alone in space. 

Meanwhile, Grace is somewhere in his early 40's when he wakes and meets Rocky. Assuming he's like 42, that's 6.1%ish of the Eridian lifespan making him appear in Rocky's eyes as some 5 year old that just pulled up driving his own spaceship.

This is an insane comparison but I cannot stress enough that Rocky is a 33 year old highly trained astronaut tasked with teaming up with some hyper intelligent alien that's only been alive for 5 years because the alien's kind decided to throw that 5 year old on a one way space trip just to see what happens.

Obviously this is a gross simplification of their ages and how aging works for Eridians, for all we know Eridian maturity can happen at a rate similar to cats, where there's a rapid maturation with a certain period of time rather than a consistent maturation over a lifetime.

But even with that in mind, Rocky and Grace both seem to be at a similar level of maturity where they're old enough to understand the seriousness of their situation, but young enough to still show the side of themselves that's naturally inclined to be some goofy nerd that's just overly excited to discover (friendly and intelligent) alien life. 

But there’s probably a failsafe in the Hail Mary that takes all their data and transmits it back to earth and Ryland definitely doesn’t know bout that.

Plleeaseeee give us some information about Grace 🙏🙏(/nf) literally anything. I'm so invested in your au its not even funny holy aohfskkakd

YIPPEE THANK YOU!!

alright here’s something I’ve been thinking of-

Eridians stay awake for very long periods of time. I don’t think it’s ever explicitly stated how long they stay awake but I know it’s a lots- like weeks at a time (plz correct me if I’m wrong.)

Grace as an Eridian is not used to this. his human psyche is still expecting to get tired after a while, and after long enough I think he would start to feel a little bit crazy. His body feels completely fine, and that makes it all the more strange as the hours pass and his just.. still going. Still awake and aware and at full brain capacity.

Eridians physically can’t get sleep deprived, they just pass out once they get exhausted enough. So nobody knows what Grace is going through- after 60 hours he gets jittery, restless, probably zones out sometimes like his human thought process is trying to go to sleep. it’s all mental and I think it would be a while before he gets used to it :]
