Will is unable to remember his father, a former Royal Marine, who has not been heard of since he vanished on an expedition to the Arctic when Will was only a baby, and who we later learn has wandered into another world and is unable to find his way back.
Will kan ikke huske sin far, en tidligere "Royal Marine", som Will ikke har hørt fra siden han forsvandt på en ekspedition til Arktis, hvor man senere finder ud af at han havde forvildet sig ind i en anden verden og ikke kunne komme ud igen.
