Tales From Year Zero
During the Kaiju attack on San Francisco, Tamsin and Luna volunteer to help the United States Air Force in the attack on the Trespasser and head for the Vandenberg base. Despite their combined forces, the aerial attack against the creature isn’t enough to do anything but wound it. When Luna attempts to fire a sidewinder down the Trespasser’s throat, Tasmin warns her of an oncoming attack. Despite her efforts, Luna is killed when the creature slashes her jet in half. The loss of Luna hits Tamsin and Stacker hard.
When Jaeger Program is initiated, both Tamsin and Stacker train to become Rangers in the PPDC’s growing forces. They are later assigned to the Coyote Tango as co-pilots. On May 15, 2016, Tamsin and Stacker fight to defend Tokyo from the Onibaba’s attack. However, during the battle, Tamsin passes out, leaving Stacker to pilot and kill the Kaiju on his own. Their efforts manage to save a young Mako Mori.
Shortly thereafter, Tamsin learns that she’s developed cancer from exposure to the Coyote Tango’s nuclear reactor. As a result, she and Stacker were retired from active duty as Rangers. Though she’ll receive treatment, Tamsin has little hope of her survival. Stacker tries to argue against the ruling, but Tamsin urges him to move on with his life.
Shortly after Stacker is promoted to PPDC Marshal, he visits a weakened Tamsin in the hospital. He introduces her to Mako Mori, the girl whom she saved in Tokyo. His gesture brings Tamsin to tears and the three embrace.
Later Life and Death
Tamsin continued to receive extensive treatment for her cancer; for a time the disease went into remission and it appeared she would survive. However, her illness returned and she died. Tamsin was buried in Hawaii, where Stacker and Mako would visit to pay their respects.
- According to the novelization of Pacific Rim Tamsin's collapse was triggered by a seizure.
- Mako and Tamsin are were said to be like "sisters" according to Travis Beacham.
