1) Who rocks the Ferris Wheel seat and who flips out and begs them to stop?

You know, I could go both ways on this one. If you go with a more myth-based characterization of Loki, he’d be the one to rock the seat to fuck with Thor, but I sort of got the sense from that flying/bickering scene in TDW that MCU Loki is a backseat driver and a bit of a fussbudget, while Thor is the daredevil.

6) Who takes photos of the other while they sleep?

Unfortunately, I read your answer first and it probably influenced mine… so yeah, I agree with you that Loki is the one who would take pictures of Thor drooling or having drawn a dick on his face. I think I’ve seen more AUs where Loki is a photographer… I guess people tend to think that’s more his style? If Thor is an artist it’s usually sculpture, since that involves hammers. So yeah, probably Loki. But I could also see Thor wanting to save the image of Loki looking peaceful, for once. He would never share it, though.

9) Who wakes the other up in the middle of the night to tell them a cool dream they had? Who has the most nightmares, and who sings them back to sleep after?
Well, we’ve seen Thor having prophetic dreams in the MCU – a talent he probably inherited from his mother. So I imagine that when he has an especially weird or symbolic-seeming dream, he wakes Loki up to ask what it might mean. Usually, Loki is grumpy as fuck at being woken up and tells Thor it just means he ate too much cheese.

Of course Loki is the one who has the most nightmares after the various things that happen to him in the movies (abruptly finding out his parentage, falling into the Void, Thanos, being in solitary confinement for a year, getting run through and very nearly dying… I’m just gonna ignore Infinity War for now). But I imagine that he also had more nightmares beforehand because he was never mentally healthy, and the experience of having been abandoned as a child might have left all kinds of psychological scarring even though he was too young to remember it. But I don’t really see Thor *singing* him back to sleep, because I don’t think Thor has a good singing voice (as far as I know, Chris Hemsworth can’t sing). Maybe Thor tried singing Loki back to sleep a few times and eventually Loki just told him his voice might produce more nightmares. So maybe Thor soothes him back to sleep with boring war stories. Or sex, that probably tires him out properly.
