i have done no research whatsoever on this but i feel like the mask could EASILY be set up to provide a dose of albuterol either at viper's command or with an integrated pulse ox sensor in her gloves maybe? or both! both is good!
i have mild asthma and i DON'T make a habit of breathing in poison, so here's my limited concept of how breathing issues would affect viper in her day-to-day life: colds and flus and covids will be hell, absolute hell and misery and impossible to work through. she would need to use a nebulizer or the aforementioned mask setup in place of an inhaler because an inhaler would likely be unwieldy given her tremors.
also i think viper uses her fancy poison science to help sage with the agents' Medical Issues. at any given time she could be cooking up annihilation or accommodation in that lab of hers and it's just a fun game of Wait And Find Out :)
now get ready, because i have a viper-related infodump that you are gonna LOVE. it is entirely unrelated to the content of this ask. i'm putting it under the read more for the sanity of anyone who didn't sign up for this shit lmao. it's uh. it got a little more wordy than i intended
i have a headcanon abt her and it involves linguistics so i know you're gonna like it. i saw that one post about how viper pronounces/enunciates things (i have been trying to find it to properly credit the op but i can't seem to track it down) and i have a theory. viper's from the united states but unless i'm missing some lore we never got info on what state she's from?
okay follow me down this train of thought rq. there's a river that runs from louisiana to east texas. it was originally named río de sabinas, which translates to "cypress river," and sabinas got anglicized as...u guessed it...sabine :) pretty much anyone who has ever spent significant time in east texas or louisiana has driven past, swam in, and/or fished in the sabine. or received those godawful river flood warnings during any rainstorm at all. i am definitely not doxxing myself rn. if i get one more call text or email about that fucking river i'm gonna toss my phone into lake pontchartrain and go off-grid forever
anyways i personally think viper's from louisiana and has cajun roots. and if there's anything cajuns love it's naming towns after rivers and then naming people after those towns.
"but viper doesn't have a cajun accent" this brings me to the next part of this infodump
the cajun accent in particular is fascinating to me at least because a lot of the idioms and pronounciations come from the merging of cajun french + american english + the languages spoken by other groups in louisiana in the 1700s + 1800s, both settler and indigenous (german, gaelic, haitian creole, spanish, chitimacha, houma, tunica, and caddo). if i start talking about cajun idioms my alligator mouth will write a ticket that my hummingbird ass can't cash so i'm just gonna move on
i was raised in louisiana and my accent was Quite Prominent as a kid. i don't know if you've ever heard a really thick cajun accent but my wife and i watched cajun pawn stars once and i had to translate for her, so there's that. mine wasn't so deep it needed to be translated but it was Noticeably Different for sure
anyways, when we moved up north i started imitating a standard american english accent because a cajun accent sticks out like a sore thumb in the north. since i moved at a pretty young age, my accent disappeared quickly, but for the first about 3 months of being up north my fake accent sounded...like a british person imitating american english. my mother also tried to change her accent, but it didn't work since she had been speaking to other cajuns for 30+ years at that point. so she had a public voice and a home voice. her public voice sounded like.....a british person imitating american english.
this is all anecdotal evidence for my headcanon that viper moved from louisiana to a northern state, maybe as a teenager or very young adult. but definitely not as a kid because i think she would've ended up almost fully adopting the dominant accent of the region she moved to if that were the case.
now, here are some of the differences between cajun english and standard american english:
first of all, cajun english is non-rhotic and standard american english is rhotic. that's gonna lead to differences in how the postvocalic /r/ is pronounced i think?
secondly, french-language phonology led to some pretty major differences in consonant features in cajun english, such as: th-stopping, h-dropping, g-dropping, l-deletion, metastasis of the /sk/ cluster, and a variety of differences in aspiration and palatization for the p, t, k, d, and g consonants. note that every single one of these factors HEAVILY depends on where in louisiana a person comes from and also where in louisiana their parents came from.
cajun english, unlike a lot of other southern regional dialects, is not subject to the southern vowel shift. this leads to some differences in nasalization, specifically for words that are loaners from louisiana french and thus contain vowels not found in standard english. typical american gliding vowels have reduced or no glide in cajun english, and the lexical stress for some words transfers to the second or final syllable of words that are typically pronounced as dactyls or trochees (those are literary criticism terms not linguistic terms but They Work Here i think). final consonant deletion + inclusion of nasal vowels with nasal consonants + transfer of nasalization to additional phonemes is also a thing that happens
the previous paragraph holds the bulk of my reasoning for this entire theory. it's also the end of my insight on this subject. i have no idea how these facts about cajun english could affect viper's current speech but i am positive someone does and i think it has to do with nasalization. i am not near as knowledgeable about linguistics as you and whoever made the viper post (op if you're reading this you're the coolest ever and i want to be mutuals) so literally everything you just read could be wrong, literally all of it.
what's the opposite of infodumping? himbo-dumping? that's me. i have no idea what i'm fucking talking about but i'm sure talking.
