Pandora is one of Miranda's friends from way back. She had been backpacking in Europe and then returned to Australia to see Miranda before going back to Europe and studying an alternative medicine.
She sparked interest in both Alex and Evan. Jealously was the main feeling Evan had, particularly after he saw her kiss Alex, but teased Alex about having a threesome with the two of them. Alex was originally interested in discussing their different views on medicine but later became more interested by the fact that Pandora seemed to be flirting with her.
