The dots show what happened to Tyson or what Tyson did on his journey.
The arrows going right to left are where Tyson met Lily, when Tyson was nearly apprehended by the military, where Tyson broke his wrist climbing over a wall, and where he stayed several night because it seemed safe.

His grandmother taught him piano. Tyson asked to learn to stop Jethro butchering the violin, at his older brother's request. 

When Tyson lies his left ring finger twitches because Sebastian broke it for lying to him.

Sebastian didn't purposefully break it, but it was a side effect of his assault.

Tyson and Jethro set up an emergency bank account using the money their mother left them. It was set up in case one of them became homeless, each year they both put £100 in the account.

At the time it was unnecessary as both had access to the family fortune, however neither would have put it past their father to cut off their access for disobeying him.

When Tyson first joined the military he trained the dogs before being moved to front line combat.

His military carrier lasted eleven years.

He is better at hand to hand combat than with a gun, he knows all the nerve points to hit.

That said, Tyson would prefer to have the option of working with a knife over having no weapon at all.

He was in the First Bangalore Pioneers as a Strategist.

When on the run from the military with Sebastian they spent two weeks in a Monestry in India so Tyson's ribs could heal. Whilst there the monk who put his ribs back in place taught him to meditate to regulate his breathing so he would be in less pain. Tyson regularly meditates because it helps him think.

Tyson had previously learnt how to calm down and breath with Jasmine, but she had taught him how to calm down after an anxiety attack. Not how to breath in a way that minimised the movement of his ribs.

His preferred drink is Jasmine and Pomegranate tea, it reminds him of his Grandmother.

She drank Jasmine tea more often than not, and her perfume smelled like Pomegranate. 

He was born on October 21st 1981.

Every weekend Jethro would take Tyson swimming in a near by creak. Once Jethro ran away from home Tyson would hang up the leather jacket his brother left him hanging from a tree branch and sit by the side of the river hoping he would see Jethro again. 

Since he was seven Tyson had wanted a dog, which is why his first job was training dogs at the vets.

To appease his father, Tyson claimed that he wanted the job to get some experience working before continuing the family legacy at Cambridge. Tyson still isn't sure if his father actually believed him, or was simply willing to make a rare allowance for his son's happiness.

He dropped out of school at seventeen to join the Army so his father couldn't make him go to Cambridge university to teach mathematics, but by this point he'd already earned his degrees (3 Ph.Ds) and any work he had left was just tidying up course work. He (technically) left a week before his seventeenth birthday, but he thinks of it as his seventeenth birthday.

UPDATE 03/10/2013 - This makes Tyson's timeline, at this point in time, read as follows: seventeen year in Cambridge, eleven years in the army (four years basic training, followed by five years training the dogs, and then two years on the front line with Sebastian), fifteen months on the run with Sebastian, four months in the Middle East, two months travelling across Europe, and just over a year and a half with Jim.

He only had two 'friends' at school: Peter Benjamin Campbell and Alastair John Mandelson. Alastair was the one who convinced him to join the military.

Even after finding out that his father had paid them to be his friends, Tyson's desire to join remained. He just needed that first push to join, to spite his father and abandon the family legacy.

Tyson played cricket on his school's cricket team every year. He was an excellent bowler and fielder, but his batting was definitely his weakest point. He wasn't bad, just not as good.

Every summer he and his brother were sent to their uncle Richard's house in Edinburgh, whilst their father went to Spain.

Tyson's father was a Professor of Mathematics at Cambridge University. Whilst there he earned the nickname "Lucifer" for his ruthless attitude and harsh marking, this nickname came from both students and teachers. He is now deceased.

This was funny to the students and some of the professors, but they didn't have the same context as the Delaney family. Their family is ethnically and religiously Jewish, the nickname left a bad taste in everyone's mouths.

Tyson's mother, whose maiden name was Anne Samantha Williams, left his father when Tyson was four.

As a child Tyson had never understood why his mother left but as he grew up he started to understand, especially after father's beating began. One thing he never came to terms with was why she chose to leave him and Jethro behind.

Tyson's older brother, Jethro Andrew Delaney, ran away from home when Tyson was fourteen. At the time, Jethro was eighteen. 

When Tyson ran away from home to join the army, he was younger; only sixteen, a few days before his seventeenth birthday.
