-sienna, natasha, and clint have a groupchat called 'strike team delta'

-coulson probably sent cute little birthday cards to a little sienna every single year since shield took her in

-steve and sienna have danced together at least once for a mission of some sort, and the poor woman had terribly bruised feet after

-sienna attends mass every easter and christmas

-when clint talks about his family, he definitely tells people that sienna is his little sister

-pepper and sienna went out for coffee at least once throughout tony's avengers qualification process and gossip about billionaire boys- pretty sure pepper knew about andrew before anyone else did.

-let's be real, a caring thor brings sienna hot chocolate whenever he brings hard ale back down to earth because he knows she doesn't drink alcohol

-maria hill and si are those friends that don't always stay in the contact due to hectic schedules, but will always lend a hand whenever the other needs it

-sienna secretly likes to get dressed up, just not in sparkles or any glitz

-many forget that english isn't her first language. she'll get really excited, a rare occurrence, whenever she hears her friends speak italian and she'll immediately switch over. si says most of her profanity in italian. if she's deep in thought, she might mumble a few english words before drifting off into her native language.

-sienna is that girl who claims to like black coffee, but dumps so much creamer in her cup when no one is looking

-steve once playfully commented on sienna being shorter than him (even though she's 5'8 and considered tall) and she straight up wore four inch heels for three days just so they could be roughly the same height

-if zerina ever began to like sienna, these two would be the coolest siblings that casually talked about the best way to strangle someone

-the hardest part of sienna's basic training was to get her to stop blocking or shying away from hits due to her mother's abuse. she prefers knives over guns because she associates pistols with her mother.

-she's not really an affectionate person when it comes to touch. she can tolerate pats on the shoulder or nudges from friends, but only if she's in a good mood. the exceptions to these rules are clint, layla, and steve, all of which sienna will receive hugs from. sometimes simmons and skye can get away with it.

-sienna herself is a naturally impulsive person, but when steve and clint are around her mom friend mode is activated.

("rogers, you jump off that roof, you'll break your neck and no amount of special serum will save you. just take the stairs.")

-people are usually intimidated by this world-class assassin and avenger who wears all black, is fairly tall, and has a resting bitch face when they first meet her. bruce also thought her pretty scary even after the battle of new york, but that changed when sienna came over to stark tower to teach pepper to make halo-halo. she wore a cat sweater, played classical music, and ranted to pepper about a tv show she was watching. she still had like eight knives on her, but bruce doesn't think she's as scary anymore.

-she has trouble sleeping in places she doesn't feel safe. she never gets a full night's sleep during missions. she only gets a good amount of hours on certain shield bases. si loves clint's family farm because she can fall asleep very easily there (only if the kids are quiet).

+ most likely more because i have so many for my bby

why am i so attached to her like these are some of these are so cute and si being happy makes me happy
