chunk: Grant learns the Kirbys are actually a middle-class divorced couple, who are looking for their son Eric, and Amanda's boyfriend Ben, who have been missing on the island for eight weeks. Later, the group finds the parasail with Ben's corpse attached. The group takes the parasail, and then encounter raptor nests. They find an abandoned InGen compound, where Amanda is ambushed by a raptor. The group manages to trap it, but it escapes and contacts the rest of its pack. The group flees into a herd of Corythosaurus and Parasaurolophus, causing a stampede, separating Grant and Udesky from the others. Grant retrieves Billy's satchel, while Udesky is killed by the raptors.
