HEADCANON: Archie has some physical disability that makes it difficult to walk. Maybe as a kid he needed crutches or leg braces? Thus he can be rather clumsy on dry land; which is why he loves being on/in the water. It's the one place where he feels strong and graceful; where he doesn't feel like a helpless weakling out of his element.
Funny that! I was looking through prompts and one said ‘one has a missing limb’ and I immediately thought of double leg amputee Maxie (which is why he wears leggings with shorts and the ONE time he runs he falls over).
With your headcannon, they’d probably bond a bit on that (though mine is Maxie was in an accident and no longer has them) although I see it as a kind of silly domestic times?
Archie would pull the ‘Babe can you get me a snack? I can’t walk that far, bad legs and all that.’ and then Maxie throws one of his prosthetic legs at him.
Serious time; Maxie (my prompt along side it or no) would be very supportive of Archie and his disability considering his work with lava is known to cause a few injuries (from serious burns to potential limb loss [if not a horrible death]) so most of his coworkers would not be without their own little ‘mark’ or three.
Maybe helping him through physical therapy to better steady himself and not being too anal at certain times when he knows Archie’s having a bad day?
Your idea could totally work!
