The CW is adding more residents to Central City, Deadline reports.
Cosnett will play Eddie Thawne, a recent transfer to Central City's detective squad with a dark secret. Panabaker has been cast as Caitlin Snow, a bioengineer who lost her fiancé during an explosion at S.T.A.R. labs.
Caitlin Snow also happens to be the name of DC's latest incarnation of villain Killer Frost, while Eddie Thawne sounds very similar to Eobard Thawne, the man who becomes Professor Zoom/Reverse Flash.
