 Leon is the first to suffer this fate, shortly followed by a panicked Shona, and Chrissie, whose rescue of Lucy from a passing truck puts her in fear of her life.During their search they find Gerry, who has escaped from hospital, and travel to a top-secret base on Astrid Island; the group are surprised to find their friends who had disappeared, but are dismayed to find they have the mentality of seven-year-olds, and appear black on an infra-red camera (according to a research document, they have been "frozen in time").After the splitting of Gerry and Simon, Harry and Lucy realise that the eyewitness was actually watching the two of them in the water, just before they split.
