Iris West-Allen: Her. Dr. Komiyo Hoshi.
Cisco Ramon: Hoshi... She went missing 4 years ago. She's an astronomer out of Tokyo with the power to fuel starlight, but her meta-powers aren't precise enough to do the kind of damage you showed me in those photos.
Kamilla Hwang: What if she used the Photon rifle to focus them?
Cisco Ramon: Good thinking, maybe the reflector chip could condense her UV photon emissions.
Kamilla Hwang: The rifle is the weapon.
Cisco Ramon: No, she's the ammunition.
Allegra Garcia: So Black Hole turned her into some kind of evil light doctor.
Cisco Ramon: So we've got a brand new, more powerful, murder-happy Dr. Light on our hands. Another new meta surprise courtesy of Earth frakking Prime.
