Callum and Connor Reilly (born Callum and Connor Farnsworth) are twin CHERUB agents.
PHYSICAL: The twins are excellent long distance runners. They are not particularly strong, but a fitness program focusing on strength training has helped with this problem.
COMBAT: Exceptional unarmed combat skills. Instructor Takada has tailored both boys skills to their physiques. In Maximum Security, the twins fight with a team effort, overpowering an opponent by temaing up and attacking simultaneously.
ACADEMIC: Bright, intelligent and enthusiastic kids with great language skills and a genuine appetite for learning.
LIKES: Reading, athletics, watching movies, girls.
DISLIKES: Being mistaken for the other twin.
The twins were taken into care in 1997. They had suffered physical and mental abuse at the hands of their mother. She was jailed for 18 months for neglect and barred from all contact with her sons. Callum and Connor were deeply disturbed when they were first taken into care. The twins barely spoke until they were seven years old. In 2003 they were recruited into CHERUB.
Callum and Connor both entered basic training together, and were out in the same team. On day 26 of training, Callum suffers from a fractured wrist, which he gained on the assault course, and Connor is paired up with Gabrielle. After James Adams gets back from his mission at Fort Harmony, Callum has finished his basic training, and becomes a grey shirt cherub by kyle blueman who was on a recruitment mission.
Man vs Beast
The Twins were on a mission in Australia, and returned to campus in November.
