The Doctor and Adelaide Brook's arc in this story is almost similar to that of Jack Harkness and Gwen Cooper in Torchwood (2006) (TV Series). In the spin-off series of Doctor Who, Gwen Cooper is defiant of Jack Harkness and she questions and challenges his leadership. Adelaide Brook is defiant of The Doctor and questions The Doctor's actions when The Doctor saves her, Yuri and Mia and is ungrateful to The Doctor. See more
