Okay we know shanon won't talk about the great gulon incident because she accidentally hyped it up too much, but have we considered the much funnier option?? Keefe. Keefe has hyped it up too much. It was NOT a big deal but he's been telling vague stories of it for years now. All of his friends make it seem huge. He is in over his head. He is so scared. His entire reputation is riding on this. They cannot find out.
headcanon that sophie slips into english sometimes when she's surprised or startled or otherwise overtaken by a strong emotion. mostly when she's the first one to speak, or she uses a phrase that doesn't have an elvin translation (as a sort of parallel to how sophie can't translate some spoken elvin phrases). she has no idea though since she canonically has a hard time telling english and elvin apart.
things that would be entertaining to throw this into:
part of why fitz gives her surprise hugs and gifts so often is because a small part of him is hoping for a little "oh my god!" and he really likes that he's one of relatively few people she knows that can translate it
it is EXTREMELY funny to fitz to alternate between using elvin and english in a conversation w/ her and watch her unconsciously flip between the two depending on what she last heard. (sophie foster is literally the only elf ever that could confuse the two, w/ how different the languages are.) it is also one of his favorite methods for spoiling biana's fun when he suspects she's trying to spy on them
sometimes sophie starts ranting in english without realizing it. it only makes her angrier when she gets blank stares from, say, sandor, and then she storms off. they have no idea what the deal is, but those were some angry consonants.
the polyglot aspects of keefe's brain mostly interprets language by "oh that's writing" and "oh i heard that" and "oh i guess that other thing means something". which sometimes looks like sophie throwing her papers down and exclaiming something in english only for him to counter in egyptian and them going back and forth like that for a while and then keefe asking a question he saw on a french sign once, and then you check in on them again ten minutes later and they're...using australian sign language? as far as keefe's concerned they only made one language switch (spoken "enlightened" to sign), and everyone else is like. no. (sophie can canonically tell english and french apart.)
ik it's not spoken, but i think that when sophie's writing for herself, she writes in english since that's what she grew up w/. and sometimes mixes up writing in standard elvin versus black swan cypher runes. so sometimes people in study hall are like "hey can i see your notes for multispecial studies?" and she goes "hopefully you can read my handwriting" and passes over an extremely cryptic mix of 'human' and 'rebel runes'. they pass it back to her wordlessly and uh, where'd all the rumors about writing in code for confidentiality come from...?
dex knows a decent amount of english from his mom's romcom movies, but he's not quite fluent like fitz or sophie. so sometimes the best he can do is pick out pieces he understands, attempt to fill in the blanks, and attempt to pick the best movie quote for the situation. it is social russian roulette at its finest and has derailed multiple team valiant meetings
Lady Gisela bringing tam into the neverseen was really funny to me because istg she was like "hm, bringing keefe into our organisation didn't work out... let's get the emo keefe"
i don’t know if anyone else has already said this but it occurred to me today that saying “twin” would not be slang, much less positive, in the lost cities?? like that is NOT twin actually
