Gloin actually explains this a bit during the Council of Elrond.
`It is now many years ago,’ said Glóin, `that a shadow of disquiet fell upon our people. Whence it came we did not at first perceive. Words began to be whispered in secret: it was said that we were hemmed in a narrow place,…
"The thing is, Steve and Bucky’s friendship wasn’t just a "they grew up so they’re as close as brothers," thing, it’s way more dynamic than that. Their relationship may be symbiotic, but it was never particularly balanced. Growing up, Steve was sickly and physically weak but had precisely the same personality as he does now: unendingly hopeful and moral, with no conception of backing down from a fight. Hence why he’s constantly getting beaten up, with Bucky having to wade in and finish those fights for him. Bucky is incredibly protective of him, which must have caused a fair amount of confusion when Steve turned into a near-indestructable supersoldier.
It’s a classic partnership between idealism (Steve) and pragmatic cynicism (Bucky), with Bucky playing the role of Steve’s protector and #1 fan. It takes the supersoldier serum for everyone else to realise what Bucky knew all along: that Steve is an inspirational figure, destined for great things. There’s this beautiful transitional moment in the first Cap movie when Steve has just rescued Bucky and the other soldiers from the Red Skull’s lab, and Bucky calls out for everyone to cheer for Captain America. This is basically the first time Steve has ever received outside recognition for being the person he is, and you can tell that while Bucky’s happy for him, he’s also a tiny bit resentful because he knows that Steve is no longer “his”. The tables have turned, and now Bucky is walking in Steve’s shadow, rather than the other way round.”
I think the best thing about the Iron Bull/Dwarfquisitor ship is the spooning. Iron Bull curled around her, her entire body pressed up against his torso, completely engulfed by his mass. Bu t what if Cadash tries to be the big spoon and ends up looking like a dwarf-shaped tumor clinging to his back.
Imagine Varric walking in during an emergency and just laughing so hard he falls down because she is awake when IB isn’t yet and she can’t move and just looks at Varric for help.
