Project Hail Mary will Not escape my crossovers statement I just had the extremely funny scenario pop into my head of Ryland Grace encountering the Wingfeather Falls children and all their friends.
So imagine there's like some sort of ball or event going on at Castle Rysen (I headcanon that ever year they have a massive celebration on the date the war ended) so EVERYONE is there, the three Wingfeather kiddos, Sara, Maraly, Mabel, Dipper, possibly Pacifica depending on when this is. And it's gotten late and Kalmar has gotten bored, so he's dragged all his friends off somewhere and they find a secret passage in the castle (as one does) and when they open the door on the other end-
-they are on a beach. But it is not Anniera's beach. No, they have wandered through a portal into Ryland Grace's biodome on Erid.
Anyway, the Wingfeather kidlets immediately clock that this isn't Anniera, Kalmar spots Grace's house and immediately decides to run over and say hello. The other kids, a mix of exasperated, fond, confused, amused, and worried, run after him, but Maraly's the only one who gets anywhere close to keeping up with Kal.
What DOES stop Kalmar in his tracks is when Ryland Grace steps out of his house, sees a child running towards him and immediately snaps into teacher mode and yells "No running in the halls!" and Kalmar recognizes the tone in his voice and skids to a stop, surprised.
The other kids catch up and Grace finds himself confronted with a gang of middle-schoolish aged kids who start peppering him with questions and immediately decides he must be hallucinating, but it's kind of a nice hallucination so he rolls with it.
The kids keep asking where they are so he tells them, "On Erid" and that makes so many more questions so he makes the kids all sit down, drags a chalkboard out of his house and starts explaining what and where Erid is as if he were in a classroom back on Earth, which works, because all the kids are aware of Earth.
This scene of Grace holding the whole gang of kids (even the notoriously adhd Kalmar) absolutely enthralled as they learn about space is soon witnessed by Artham, who tracked down the kids when they went missing, and Rocky, who came to visit Grace. They're both baffled but amused and they stand and watch for a little while, then, almost in unison they decide that they should PROBABLY do something and walk up to the group. Rocky asks Grace what he's doing and Grace replies, "teaching a group of kids I hallucinated, why not, right?" Artham asks the kids what they're doing and Kalmar jumps up and yells, "We're learning about space! :D"
Chaos erupts as several things happen at once: 1. Rocky tells Grace he can see the kids too, so Grace is not hallucinating, 2. Grace notices Artham and goes, "?! angels are real now too?? wait am I dead? no, Rocky's here- Rocky, are we dead?" 3. all the kids (minus 1) are talking at once to Artham.
And 4. Leeli sneaks up to Rocky and starts listening intently to him and then scares him half to death when she perfectly replicates the words he's saying on her whistleharp, leading Rocky to exclaim, "YOU HAVE HUMANS WHO CAN SPEAK ERIDIAN QUESTION" to Grace xD
That's it, that's the scenario, I just think it'd be hilarious. The Annierans would be more than happy to give food and stuff to Ryland and the Eridians, and the Eridians probably give them stuff in return (like zenonite, Fiddleford is the only person who knows how absolutely NUTS it is. Fiddleford definitely has some long and interesting conversations with the Eridians about technology and building things and probably helps them upgrade/work out tweaks in Grace's biodome. He also has some fascinating and amusing conversations with Grace, they'd probably have fun talking science to each other xD he'd also have sooooo much fun talking to Rocky ehehehe)
Kalmar spends waaaaaaay too much time trying to convince Grace to let them "borrow" the Hail Mary. He almost succeeds but Janner shows up and tackles him.
Leeli picks up Eridian terrifyingly fast. Why wouldn't she, afterall, her entire thing is music, and she already fluently speaks another language (dogspeak xD). The baby Eridians are especially enamored with her, but even the adults are fascinated by her mastery of their language. Grace is slightly irritated and keeps muttering that human children pick up language faster and more fluently than adults.
Grace explaining to Kalmar, Janner and Artham how he ended up in space and he gets to the part about how he didn't want to go to space and tried to run and the three of them just get really quiet and solemn and he stops and asks why and Kalmar finally just kind of shrugs and says, "We ran too. Also Janner had to get sacrificed to restore our people." "... WHAT." (bonus if this leads to the Wingfeathers explaining the First Well and how it works and then they're like, "Oh hey! do you want some? Since you said this planet hurts you and also you're living around people who live a LOT longer than humans and the First Well water can prolong people's lives, would you like that?" and Grace starts crying and later gets to tell Rocky that they figured out a way for him to live longer and if Rocky could cry he'd be crying too, "Grace will live long time question?!" "Yeah, we tested it. I can't even feel the extra gravity anymore and they said this water made people in their world live hundreds of years. Kalmar said he'll bring over a couple? barrels?? of the stuff." "GRACE NOT DIE SO SOON AMAZE AMAZE AMAZE" ;-; )
Anyway. I feel like there are possibilities here.
