 Lucas North appears to be a person divided between who he was prior to his incarceration and who he has become since . Richard Armitage has described Lucas as " very ambiguous , but quite open with everybody " and " a bit of a double @-@ edged sword , so he 's not completely white . He 's a bit of a dark horse . " He is also described as having " no knowledge of how damaged he is emotionally , until memories start to work their way to the surface . " Following his release from prison , glimpses of him adjusting to the outside world — such as a scene in episode two in which Lucas lies on the floor rather than in a bed in order to sleep — reveal to the audience how much he is struggling , though he keeps it hidden from his teammates . Lucas also fights very hard to be accepted and to regain Harry 's trust , but he does not always play by the rules . In the series seven finale , Lucas admits to having blamed Harry for his ordeal . However , in series nine , Lucas also believed he deserved being tortured , as penance for bombing the British Embassy in Dakar .
