Arthur Teller worked with Ameila many years ago before she "died". He was very focussed on numbers and was doing tests with her. Some years later, Arthur meets Martin who tells him about his son, Jake and that he is very focussed on numbers.
It is known that when Teller was studying the numbers, he used his daughter as his assistant who wasn't very happy when Teller lost everything and dragged her down with him.
Teller developed a relationship with Martin as a friend as he was very keen on finding out more about Jake. His death came as a shock to Martin.
