Alice Carter

Alice Carter (née Alice Sangster, previously Melissa Moretti), born 5 August 1975, was the daughter of Jack Harkness and former Torchwood Three operative Lucia Moretti, an Italian. She was also Gray's niece.

Biography
In 1977, Alice was put under cover by her mother, Lucia, who died in 2006 of natural causes. While Alice's parents were recorded as James and Mary Sangster, the British government knew they did not exist. (TV: Children of Earth: Day Three)

Alice lived with her son, Jack's grandson, Steven. Like every child on Earth, Steven was briefly taken over by the 456 in 2009. (TV: Children of Earth: Day One, Children of Earth: Day Two, Children of Earth: Day Three, Children of Earth: Day Four)

Following this takeover, Alice was visited by her father, who wanted to perform some tests on Steven. She denied Jack the opportunity; she saw the harm that might befall her son should he associate too much with his grandfather. She had told Steven Jack was his uncle, presumably until he grew old enough to realise Jack did not age and be told he was actually his grandfather. (TV: Children of Earth: Day One)

Agent Johnson and her men took Alice and Steven into custody to use against Jack. (TV: Children of Earth: Day Three)

On Day Five, Alice and Steven were released from prison. Jack needed a child to reverse the signal that had killed Clem McDonald, to use against the 456. With no other child available, Jack used his grandson, despite Alice's wishes.

Steven died. Afterwards, Alice encountered her father in a hallway, but turned and left him without saying a word. (TV: Children of Earth: Day Five)
