you know what. the fact that odin has to go into the odinsleep (effectively a coma in which he - and all of asgard - is incredibly vulnerable) at regular internals all throughout thor and loki's childhood is a really underappreciated bit of backstory!
like... thor and loki have effectively grown up with a chronically (well. episodically, but consistently) ill parent. that's going to have a profound effect on them. it's not something i've experienced myself, so i'm just guessing, really, but some thoughts on what those effects might be...?
a sense of extreme instability in their attachment to odin, especially when they're very young. no wonder they both have abandonment issues!
before they're old enough to understand, they're going to experience it as: father is here but he is refusing to engage with us, and no-one is sure when he will again. have i done something wrong? am i just not important enough? this might be exacerbated by people trying to tell them that it's "meant to happen", "for a higher purpose", "under control", etc.
once they ARE old enough to understand, they will naturally see it as very dangerous and frightening. their father is the universe's miraculous, invulnerable protector... until he isn't. what if it comes on unexpectedly, somewhere dangerous, somewhere no-one can find him? what if a war breaks out? what if he never wakes up?
the odinsleep is linked to odin's powers and odin's responsibilities to the kingdom. he exerts himself until he falls into a coma. For Them. it's a kind of martyrdom, and it must induce a lot of survivor's guilt in his family.
there's a lot of cognitive dissonance around vulnerability, especially odin's vulnerability. the royal family must always present a strong and united front to the world, and questioning or undermining odin, even in private, can have severe repercussions. and yet odin regularly enters health crises that they can't not respond to. yet more unprocessed and uncommunicated emotions in the house of odin.
the odinsleep seems to be the brink of death, so in a way, odin dies over and over - and his family brace themselves for grief over and over. it must make it harder to admit any flaw in him, much less the vast extent of his abuse, when they're constantly reminded of what the loss would be like.
but at the same time... there might be some peace in his absence. relief at the withdrawal of a tyrant. which will only cause further guilt and anxiety in them all, and maybe lead to them policing each other harder to compensate...
every time odin goes into the odinsleep, someone else has to rule. at first, this will be frigga - which means, when they were young, thor and loki would lose most of their contact with both parents at regular intervals. which might contribute to their closeness with each other, as the only stable connection. and later on, it would probably mean thor had to be regent (to the realm at its most vulnerable!) - so he would lose a parent figure and very suddenly have to grow up (and possibly leave loki behind)...
it's not 100% clear... but it seems likely that the odinsleep is something the next king will eventually inherit. thor's future promises untold power and untold sacrifice, and always has. a king is powerful, and a king is exposed. this complicates thor and loki's power struggle in a really interesting way! it's not just: let me be in charge. it's also: let me take the danger, i know how to handle it better than you...
hmmm. there is probably much more to be said here but these are. some initial thoughts
