The neck line

After an incident in Afghanistan, a mission gone wrong, Tyson doesn't wear anything with too tight of a collar.
The clothes that he wears are either very loose and bellow his collar bones [t-shirts and polos] or stop on the collar bone and are tight enough that they can't slip any higher [basically anything else other than dress shirts and formal dress shirts*].
When he wears a dress shirt he doesn't do up the top button and lets the tie or bow tie [or any other type of fabric worn around the neck] keep the collar closed. When he wears a formal dress shirt he'll close the top button but keep the neck wear loose to avoid triggering any flash backs. 

*Having come from an upper class family Tyson considers anything worn on the torso that isn't a vest or item of clothing worn over a shirt [blazer, jacket, coat, et cetera] to be a dress shirt. What most people would normally call a dress shirt Tyson calls a formal dress shirt.

Tyson's eyes

Tyson’s eyes are brown (Hazel). In this particular picture of Damien Molony his eyes are green but if you look at others his eyes are clearly brown. This is very common for people with hazel eyes, so I will always say that Tyson’s eyes are brown but on occasion they may have a green hue to them.


Tyson’s brother’s, Jethro Andrew Delaney, eyes are usually green but occasionally become green, like their mother’s, Anne. Whereas Tyson takes after their father, John, and his eyes are usually brown and only occasionally green. Due to the resemblance to his father’s Tyson has never liked his eyes, except for when they become green; which happens more in the summer when the brighter light brings out the green pigment better than it does during the other seasons.

When Tyson served in Turkmenistan and Afghanistan, 2001-2006 and 2006-2008, the brighter light in the Middle East meant that Tyson’s eyes were green more often than they are now that he is in Britain. This also applies to the time Tyson spent running away from the army both with and without Sebastian, 2008-2011.

Christmas or therefore lack of.

Head Canon:

Tyson doesn’t celebrate christmas. Having grown up in a Jewish household he didn’t as a child and without a family he sees no need to now.

Unless he knows that someone definitely does celebrate the holiday Tyson doesn’t both getting them a gift or a card as he knows that most people would then feel obligated to get him something, and he doesn’t want anything*.

The only difference is that he is more charitable, though only because it is nearly impossible to turn a corner without finding a donation box set up specifically for christmas and Tyson will always give if he has money on him at the time. 

*That statement isn’t entirely true. There are items that he does want but he’s has never been in a position where he has been lacking money. With access to the family fortune Tyson doesn’t need to wait till Christmas to get something he wants.

Even then he doesn’t buy all that much. He limits himself to buying one book a month and, unless it was a digital book, at the end of the month the book will either be placed in the library at the family manor or given to a charity shop. 

Tyson's Education

The secondary school Tyson attended was Cambridge International School, a private school. He attended until he was fifteen when his father had him moved to Cambridge University, four years early.

His father was able to do this because he’d held a position at Cambridge University as a Professor of Mathematics for over twenty years.

At Cambridge Tyson studied mathematics and military history. His anti-war father disagreed with his choice of minor but agreed to let him continue it rather than taking political studies. Tyson was also able to study law at Cambridge for half a semester when he finished mathematics early. 

Word related head canons

Burn

Since a young age Tyson had been scared of fire.

Whilst his brother would watch the flames in the fire place and be transfixed by how they moved, Tyson would stare at the flame to make sure they weren’t touching anything flammable. As if looking away from the flames would mean that the house would suddenly turn to ash as the fire burned it down.

Quiet

From toddler to early teen Tyson was quiet, father was working.

For the rest of his teens Tyson was quiet, father was working.

Twenty to twenty seven Tyson was quiet, there was work to be done.

Traveling to India Tyson was silent, Sebastian was talking.

Fleeing back home Tyson was silent, the police were coming.

Hiding from the Colonel Tyson was silent, everyone was coming.

Now safe and sound with darling dearest Tyson was resounding, the consulting criminal was calling.

Tyson's gadgets.

Tyson buys gadgets he thinks will do a good enough job for his purposes then hacks into them and edits the softwear / hard wear to fit his needs. Using the technology in his owner's compound Tyson learnt how to edit his devices to fit his needs.

Due to the family's wealth money isn't an issue but he prefers not to buy anything overly expensive as most of the time he can find a relativity cheap gadget to get what he wants done; and its less likely to get stolen. Tyson's three main gadgets are his phone, tablet, and laptop.

Laptop

Tyson mainly used his laptop to write. It doesn't show very well when he speaks but Tyson is very literate and enjoys writing stories.  The top or back laptop is "decorated" with stickers ranging from the stickers that come on apples to promotional 'Pedigree' stickers that came with the dogs treats. His nephew has also contributed several stickers to it.

He uses the laptop's keyboard - though he's replaced alternate keys to make a black (keys with white text) and white (keys with black text) checkerboard board, similar to this but with normal laptop keys not Mac keys  -  but has a separate wireless mouse.

Phone

Like everything in Tyson’s life, his phone was well organised. There was a code for everything in his phone: resources (ammo and gun suppliers, knife makers, fabric makers, tailors, butchers, bakers, anything Tyson used) were listed as different pieces of classical music, for example, his German tailor was listed under Schäferoper, one of Wagner’s operas.

By default, Tyson's phone displayed all manner of incrimitaing data, but if he enters a different password when unlocking it, his phone will enter a mode where only data that he specifically flagged as safe will appear; it was easier than attempting to tag everything that wasn't safe.

If the person matters to Tyson and is ever likely to call, Tyson will give them a personalised ringtone. His default ringtone, for people he doesn't know/those he hasn't gotten around to given a specific ringtone, is the chorus of 'Pumped Up Kicks'. Whenever Tyson is out and about, his phone is on vibrate, but whilst at home he finds the music more useful to avoid unnecessarily springing into action.

Tablet

For Tyson, his tablet is purely person. His laptop will be used for work, but his tablet is just for entertainment purposes: for reading digital books, listening to music, and watching films. He uses the tablet for these things rather than his laptop because it is more portable than the laptop and needs charging less often.
