the flash danielle panabaker rick cosnett 'The Flash': 'Arrow' spinoff casts Danielle Panabaker, 'Vampire Diaries' villain Rick Cosnett

The CW’s pilot “The Flash” — starring Grant Gustin — just added two more faces to its ever-growing cast.

The “Arrow” spinoff has cast “Necessary Roughness” alum Danielle Panabaker and “The Vampire Diaries” villain Rick Cosnett, Deadline reports.

Panabaker joins the pilot in the role of Caitlin Snow, a bioengineering expert who lost her fianc√© during the particle accelerator disaster at Central City’s S.T.A.R. Labs — and also the person who becomes the freezing baddie Killer Frost. Will Panabaker make the leap from good guy to villain on the show like in the comics?

Meanwhile, Cosnett — recently seen on “TVD” as the sadistic professor Dr. Wes Maxfield — will play Detective Eddie Thawne, a new Central City PD recruit with a mysterious past and a dark secret. In the comics, Professor Eobard Thawne is also known as Professor Zoom, one of The Flash’s most formidable enemies. Will Cosnett continue his reign of villainy on “The Flash” as well?
