Recap / The Sarah Jane Adventures S1 E9-10 "The Lost Boy"

A news report on a family searching for their son, Ashley, who has been missing for five months, brings shock to Sarah Jane, for the missing boy Ashley looks exactly like Luke. Mr Smith compares their DNA, and confirms that Luke and Ashley are genetic matches, claiming Luke was not 'grown' by the Bane, but was kidnapped and experimented on.

Chrissie Jackson calls the police and reports Sarah Jane as a child abductor. Luke is released into the custody of his 'real' parents, Jay and Heidi Stafford, and Sarah Jane is arrested, only to be released by intervention of UNIT. Mr. Smith informs Sarah Jane that a research facility, called the Pharos Institute has been experimenting with psychic energy, engineered from alien tech. At the institute, she encounters a boy genius, named Nathan Goss, for whom she feels strangely uncaring.

Back at the Stafford's house, Luke is introduced to his room, and is suddenly locked inside by his 'parents'. Mr. and Mrs. Safford turn on their television and report to a being they call "the Xylok", saying that they have captured Luke.
