Tiera after chosing the blue pill, during the events of A Life Less Empty
Tiera was a hacker in the Matrix and the protagonist of the Matrix Comic A Life Less Empty who, after being given the choice, took the blue pill.
History
Early life
She led a seemingly carefree life as a child (and had a white rabbit stuffed toy), was interested in computers as a girl, and became a hacker extraordinaire as a woman, involved with other elite hackers and admiring figures like Morpheus, Neo, Trinity and all "the other Myths and Legends".
Choice
Then Morpheus came into her life, offering her the truth about the Matrix and the choice between two pills, one red which "would be the total alteration of [her] life... A brave new world of the unknown, to be reborn anew. And learn the truth about everything." The other was blue, and meant "stop". Scared, she took the blue pill, and spent the rest of her life wondering would have happened if she had accepted his challenge.
Aftermath
She continued to live in the White Rabbit Hotel area and read books like Memoreaze, Simulacra and Simulations, Interfazed, Byte Me, Hackers Bible and Freud's "memo's" on computer as well as getting The Daily News newspaper. She still seemed to know something of the real world and the true nature of the Matrix, describing herself as "a pitiful shell of a human. Nothing more than a friggin' ghost in a machine".
