So I Have The Mental Capacity To Become An Absolute Expert In A Random And Mostly Useless Field Of Knowledge,

Anyone else remember when Simon and George were gonna raise baby out if there sock drawer? Cause it was so pure I love them so much!

Simon and Alec developing a friendship is something I need to see in my lifetime. Please.

I want more TMI gang content but like. Not just the core ships. I want to see Clary and Magnus’s relationship now. Jace and Simon. Alec and Clary. Izzy and Jace. Simon and Magnus.

This is so Sizzy core

Someone help me, it's 2 in the morning and I'm thinking about rereading Shadowhunter academy again.

Jace being so randomly over protective Simon is sooo funny to me because Simon did NOT ask for that 😭😭

Like in GOTSM when Lily was talking abt how Simon bit Jace badly and Jace was like “he did great actually 🤬🤬🤬” or city of fallen angels when Simon was like “I have a roommate” and Jace was like “I’ll fight him” and Simon was like “…okay…”

Jace;

-Simon and Maryse cooking on family nights

-Maia being a mom friend

MY TMI GANG HEAD CANNONS

- Alec can, will, and has forged Mayrse's signature, to bail Jace and Izzy out of trouble, with the clave.

- When Jia was consul, she always has them file two reports, one for records and legal purposes, and one with what actually happened, cause you know they 'smudged' the truth a little (a Lot.)

- Simon as a toddler was the type to put anything he could reach in his mouth, rocks, mud, bugs, he'd tried to lick a lit candle at least once.

- Clary was and ankle bitter 100%- much to Luke's amusement.

- Mayrse and Simon have the same coffee order - and and Amazing son-mother-in-law relationship.

- Clary Izzy and Magnus regularly have sleepovers and just rant about their boyfriends all night, and walk out with amazing manacures...Alec is not allowed in the loft during these.

- Alec and Magnus have a ranking of who they can ask to babysit Max and Rafe...it's based one how likely they are to give their toddler/baby deadly weapons and magical ideas, Jace and Izzy are towards the Bottom.

- Simon is either the best with baby/house sitting...or they place is in fire in 1/2 hour...there is no in between.

- Simon is the only one of them who can actually cook worth his ass...and no Magnus, elabrote meals summoned from around the world don't count.

- Alec is low-key a pyromaniac.

- They all have rotations to make sure that no of them are alone a night, cause they all have nightmares.

- one of them definitely has a very detailed kill list ..very detailed...and elaborate

- Simon takes April fools very serious...no one knows how he does it...but there all extra nice to him towards the end of March.

- Izzy and Magnus have drilled a fashion sense into everyone they regluarly interact with.

- Jace and Simon are both polygots and often have arguments switching between several languages...Alec has giving up trying to understand, and Magnus laughs his ass off, at his frustration.

- Izzy has is the type to fake a different accent everytime she order...much to the confusion of the barista at Java's.

- Eric named the band The Mortal Instruments...not Simon.

- Raziel killed George to get back at Simon.

- Raziel has watched the gang because he know if someone doesn't ...there gonna fuck up the world

-Simon absolutely despises angels...and low-key thinks Azazel was a Vibe... Clary thinks it's whatever...the Lightwoods are very concerned

- Alec has set off fireworks on the institute roof once..he never got caught

- Magnus gets a tattoo of their intials..after they all pass

- Sizzy has an open relationship for sex..but not dating...they also have a mission to sleep their way through New Yorks age appropriate shadowworld population.

- Simon know way to many people...like way to many people.

- after watching Spiderman No Way Home..they all just kinda clung to Simon..it hit too close to home.

- They all tease Jace over the fact that he's the only one to never meet Raziel despite the fact that his the reason he was summoned twice now.

- Jace is ridiculously vanilla....Clary is less.

One thing that I’d love to see more of is the dynamic between Simon and Catarina. She said he reminds her of her son?? And Simon is severely lacking in a stable mother figure??? I wish we got to see him from her perspective. Their relationship was my absolute favourite thing from tftsa, I want more.

Ok I've seen kit and jace but why is nobody talking about kit and simon????? Here are my random headcannons ig

Kit would be over at simons place whenever he was in the area or just needed space from everyone else

Kit would side with simon against jace whenever sarcastic bickering came into play

Kit, simon and maia just being absolute nerds

Kit and simon quoting vine on a daily basis

Kit cooking with simon and isabelle (more like kit and simon teaching izzy to cook)

Simon introducing kit to emo bands

Kit playing dnd

I CANNOT BELIEEEEEVEEVVEEREHHENEW😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭

I love this so much

Carstairs-Gray family Headcanons!

They’re all super close and enjoy spending time together

Kit practically WORSHIPS Tessa

Jem spends a lot of his free time just singing, because his lungs are finally able to support all that air

He sings beautifully, which made Kit make so many remarks on how Mina will inherit his singing voice, which she does not

She does have an incredible voice, but it’s nothing like Jem’s; it’s Tessa’s, but they don’t know that because she never sings

Jem keeps denying Mina’s physical similarity to him, on the account of “she’s so beautiful, who could she POSSIBLY look like besides Tessa?”

Kit picks up painting, and since his bedroom window faces the garden, it’s perfect inspiration

Kit introduces Jem to rock and metal, and to everyone’s surprise, he loves it

Mina is besties (and eventually Parabatai) with Clace’s future kid, creating the next Carstairs-Herondale duo

Kit secretly learns Mandarin to surprise Jem, but he sucks at keeping it secret so Jem has to pretend to be surprised

Kit still has no idea he knew

The moment Jem and Tessa realize that Kit was deprived of love as a child, they shower him with love and do their best to give him the childhood he never had

A part of that is Tessa reading to him and Mina before bed (‘The Beautiful Cordelia’ anyone?)

The first time Kit calls Jem ‘Dad’, he cries

Tessa doesn’t cry when he calls her ‘Mum’, but she comes very close to it

Jem teaches Kit how to play the piano, because Kit thinks the violin is too hard (he’s right)

Mina, however, LOVES the violin

Kit buys her a violin of her own for one Christmas, and he manages to do so without complaining about the prices

Jem is a surprisingly good cook

Tessa is not

Always a good day when Clary and Jace show up

Mina has a period where she tries to learn every language she can; Mandarin from Jem, Welsh from Will’s ghost (because obviously he’s there), Indonesian and Spanish from Magnus, Hebrew from Simon

Simon loves hanging out at their place because of all the books Tessa has

Kit takes Jem to a ‘Sabaton’ concert once, and manages to convince him that ear protection won’t stop him from hearing the music

Jem enjoys every second of it, and also enjoys not having any damage done to his hearing

Mina loves climbing trees

She chooses to fight with a spear, and not even she is sure why, but she enjoys it

She also gets really, really good at it

Jem tends to tell her ‘use your voice. Sing, scream, talk, lecture. Because you might not always have it.’ And she takes him seriously and never hesitates to speak her mind

She’s the flower girl when Kit and Ty inevitably get married

Jem gets introduced to cars, and is absolutely terrified of them despite Tessa being an excellent driver

Kit tries not to laugh at him for it, but kinda fails

Jem doesn’t mind

Kit wants to study abroad, but Tessa doesn’t allow it

He goes to a university in London instead

Feel free to add more!
