Simon is athletic and sporty. He is one of the fittest, fastest and strongest members of the group, but he is also very arrogant and self confident. He is not unloyal but can become overwhelmed with stress, making him very challenging to get along with and leading him to make bad decisions.
Because of this, he very rarely gets along with the rest of the group, though he does start a rocky relationship with Chrissie McAteer. He realises his mistakes, but often they have caused a lot of harm. He did not mean to be a traitor, but in the stress he thought it was the right thing to do. He is later reunited with the group after meeting Vic, of aboriginal descent.
Vic shares his knowledge of the Sky Gods (Aliens) with Simon by going into an ancient cave system. Vic then helps Simon reunite himself with the rest of the group. He shows them the cave paintings and how they told the groups story. He proves himself a valuable member of the group in the end. Simon contracted the red eye and is the second last character to disappear.
