There, John, Sarah and Sam are attacked by the Mogadorians, who brought two giant monsters to hunt the trio. They are saved by Number Six and Bernie, who is actually a shapeshifting Chimera sent by John's biological parents to protect him. John and Number Six, who can teleport and can block energy attacks, continue to fight the Mogadorians. They eventually defeat them all, including the Commander. The following day, John and Number Six unite their blue rocks and discover the location of the other four surviving Lorians. John decides to let Sam come with them in hopes of finding Sam's father. They set off to find the others so they can all protect Earth from the Mogadorians, leaving Sarah and a repentant Mark, who lies to his father about John's whereabouts and returns a box left to John by his Dad that was in police evidence. John leaves after promising to return to Paradise and to Sarah.
