disturbs the Bane Mother. The Archetype awakes and proceeds to escape with visitor Maria Jackson
(Yasmin Paige
)and her investigative journalist neighbour, Sarah Jane Smith. After the Bane Mother sends assassins to kill the group, they return to confront the Bane. The Archetype saves the day by recalling an exceptionally long sequence of numbers necessary to trigger an explosion in the Bubble Shock! factory.

sets up Series 1 of The Sarah Jane Adventures (2007), depicting Luke's first day at school and his difficulties and early bonding anxieties with Sarah Jane. Luke struggles to adapt to life at school owing to his inability to lie or master humour and his apparent genius-level intellect which sets him apart from his fellow pupils. He and Maria (who is also new to the school having moved recently to the area) meet and befriend Clyde Langer
(Daniel Anthony
), whilst Luke makes an enemy of Carl (Anton Thompson McCormick), an intelligent boy who envies his effortless intellectual superiority. The friends discover that Carl and three members of staff at the school have been replaced by members of the alien Slitheen family
from Raxacoricofallapatorius, and that Luke has assisted unknowingly their plan to switch off the Sun
by providing them with the equation they needed to run the machine that will absorb its energy. Luke tricks the Slitheen into resetting their machinery and most of the Slitheen are trapped in their secret room in the school and explode. Luke, Clyde and Maria assist Sarah Jane against alien Gorgons in their second adventure, and the war-faring alien Uvodni in their third. A plot by extra-dimensional villain the Trickster erases both Luke and his mother from history in the story Whatever Happened to Sarah Jane?
, although Maria successfully restores it in the second part. Sarah Jane is forced to give Luke up in series finale The Lost Boy
when a couple allege that Luke is their biological son, casting doubts on his original origin. This later transpires to be a plot by the original Slitheen that Luke believed he had killed, who attempt to harness Luke's latent psychic abilities to telekinetically bring the Moon
crashing into the Earth. Luke and Sarah Jane are reunited after their plot is foiled.
Luke is mentioned, but does not appear, in the Doctor Who Series 4

in conjunction with Mr Smith and the Cardiff Rift
to tow Earth back to its rightful place. Following this, series two of Sarah Jane (2008) sees Luke part ways with Maria when she moves to America in the The Last Sontaran
, and befriend investigative new girl Rani Chandra
(Anjli Mohindra
) who comes to discover the extraterrestrial activities that he, Clyde and his mother are involved with. Initially, he dislikes Rani due to her replacing Maria. In series two serial The Temptation of Sarah Jane Smith
, Luke meets his grandparents in a time travel plot set up the Trickster. In series three's The Mad Woman in the Attic
(2009), an alien shows Luke a vision of the future in which he appears to be graduating from university at a young age. He meets the Doctor in person for the first time in The Wedding of Sarah Jane Smith
and assists him in defeating the Trickster for a third time. Luke is entirely absent from the two-parter The Eternity Trap
due to Tommy Knight's real-life school exams. In the series finale The Gift
, Luke and Sarah's relationship becomes at times strained by the difficulties of parenting a teenager. Due to infectious alien spores, Luke becomes sick for the first time and nearly dies, spurning Sarah Jane to take up arms against their enemy.
In Doctor Who special The End of Time (2010), Luke is saved from being run over by a car while talking on his mobile phone to Clyde by the Doctor just before his pending regeneration. The Doctor then waves to Sarah Jane and Luke before stepping into his TARDIS and disappearing.
