chess-ka:

The irritation of siblings, with science nerd Óin and bratty Glóin who keeps touching everything.

(One of the things I miss most from the movies is Óin and Glóin’s bickering. At one point in the book they have an actual fight over lighting fires and it’s gloriously petulant.)

Thinking about Mizim/Gloin grandparental headcanons is a giant squee of cute. <3

It absolutely is. 

Gloin is the most sappy grandpa who ever EVER lived. Even though Gimizh is universally considered to be Terror on Legs, he can do no wrong in Gloin’s eyes. He is utter perfection. Just mentioning Gimizh can make Gloin’s face soften into lines of total adoration. Gloin would absolutely be the one to give Gimizh a toy axe (at faaaar too young an age for it) – and watch beamingly as Gimizh proceeded to whack everything in sight with it.

Mizim is the indulgent Nanna who gives sneaky treats to her little monster. She is the one who squirrels away old clothes for a dress-up box and old blankets for fort-making. She is ABSOLUTELY the one who, instead of cleaning the small painted handprints on the wall, sticks a frame on them instead and labels it ‘Gimizh, aged 14 1/2′. She would be the one to let tiny fingers play with her glorious and abundant white mane and beard, tangling and knotting it with beads and bells which she would wear all day – no matter where her business takes her (it would take hours to undo all the snarls).
