"You know, these IOU's are starting to add up."

- Cecile flirting with Joe West

Cecile Horton is the district attorney of Central City.

Learning of the pipeline
When a police cruiser camera apparently caught Detective Eddie Thawne shooting two officers without warning, Cecile interrogates Thawne at CCPD. Despite Captain David Singh unwilling to believe Thawne to be capable of murder and Barry Allen pointing out lack of powder burns on his clothes, Cecile refused to be moved. Later, she, Singh and Barry watched security footage of the Flash fighting Hannibal Bates, who shapeshifted into multiple forms, including Thawne's. Cecile remarked that law wasn't ready for metahuman criminals. After dropping the charges against Thawne, Barry provided evidence for Cecile to exonerate Bates' other victims he framed for his crimes.

She was approached by Joe West, who asked her to help him transport some imprisoned Meta-humans to a secure location. However, she turned him down, as they could be arrested for it.

Working alongside Joe West
Over a year later, she informed Joe that the D.A.'s office had no information on Alchemy and guessed that his inquiry was metahuman related. Later, she and Joe visit Rosa Dillon at Iron Heights for information on the whereabouts of her boyfriend Sam Scudder, who gained power over mirrors, according to a former associate of Leonard Snart, who was assaulted by Scudder. As soon as they were done questioning her, Scudder appeared and broke Dillon out using meta-human powers. After Scudder and Dillon were apprehended by the Flash and Jesse Quick, and sent to Iron Heights, Barry assured Cecile and Joe that Scudder couldn't Mirror Master his way out with his cell lines with an anti-reflective material. Afterwards, she asked Joe out on a date, but he declined, stating that he had movie night with his kids.

A couple weeks later, Cecile went on a date with Joe to see The Shining at a local park. However, their date was interrupted by an attack from the meta-human Shade.
