Roxanne Adams is a former patient at Mary Hamilton's clinic.
When Alice attacked Gotham with poison infected bats, Roxanne got bitten by one of them. She was then administered the Desert Rose cure from Hamilton Dynamics and put on the list of victims from the attack. Sometime after the attack, she came into the clinic for another test. Because Ryan Wilder came into the clinic to ask a favor of Mary, Mary asked Amy to test Roxanne. Amy later noticed, in the results of these tests, that Roxanne's cancer had been completely cured.
