 While David and Sarah stay in Scotland, the rest of the group return to Australia via the same time travel portal they arrived at.Back in Australia three days from their apparent death, they find themselves visible again, and are continually pursued by Stanich.They realise that they must try to contact the aliens so that everything can be returned to normal, but they soon discover that they are suffering from a condition they name the "red-eye virus" - when an individual is stressed or fears for their life, their left eye glows red and they appear to "split", as if they are two separate people for a number of seconds, before vanishing.
