Diana's father works for Natalie's father, and when Diana's dad decided she needed a good lesson in manners and reality he sent her to be Natalie's 'friend.' Diana's father hoped more than anything that Natalie would soften the rather spoilt child he raised, admiring Natalie's cute bouncy nature and personally wishing his daughter was like her. This naturally started both girls relationship off on bad ground: Diana was resentful against her father for first refusing to spoil her and moreover putting her with a werido, and Natalie really disliked Diana person to insult her. As such for their first year of their 'friendship' Diana was a pain to both Natalie and her other friends and actually helped other kids bully them. However one day following Natalie home from school (due to them being on a play date) Diana grabbed Natalies headband and while trying to throw it into the river she slipped and fell in herself. Natalie almost instantly dived into help her and managed to drag her to the shore. While initially ungrateful this act of kindness lead to Diana mellowing out, and over the three years they have been friends has opened up to Natalie and even drove the bullies off her.
Since that fateful day both Natalie and Diana have become real friends and enjoy each others company, as in a weird way they complete each other. Diana is haughty, stuck up (not as much as she was), and yet is skilled at organisation and is defiantly intelligent and perceptive. Natalie is a little scatter brained and is spontaneous leaping in even when it will put herself in danger, yet is kind well meaning and understanding. As such Diana has come to rely on Natalie to 'humanise her' by teaching her social graces and to judge people less on who they are and more on what they do. Indeed Diana is the one who Natalie probably takes the most advice from, and although Natalie calls her colder friend out on some her more hash suggestions she can always rely on Diana to come to a well rounded conclusion that she and everyone else can understand.
Initially Diana flat out refused to believe that werewolves existed so she and her friend often argued over whether they actually existed or not, but after she was personally saved and healed by the werewolf Sage she became a due hard fan of the supernatural, further strengthening her friendship with Natalie. As such when Natalie founded the Underside of the Wolfs Paw she appointed Diana as the groups secretary and placed her in charge in setting up all the play rooms and areas on their oil tanker as she was the only person she trusted to get it done well. Diana was also the one to suggest to Natalie that they kidnap Alpha and Queen to get them to turn them, and was one of the many examples where Natalie questioned her advice. Natalie got really worried for her when Diana stayed behind on the Tanker to make sure everyone got off. She was naturally excited to hear that she would be becoming a werewolf and instantly began to organise the event with Natalie: before Ashley shut them down. And she was right there with Natalie when she reformed their old club into the Talbot Pack Crusaders, and like last time fills the role of being the groups strategist and organiser.
