Watch Out for Arden Cho in ‘Chicago Med’

It turns out Dr. Ethan Choi has a sister… but she may not be the ideal sibling.

Arden Cho will join NBC’s “Chicago Med” in a recurring role as Emily, playing sister to Ethan, played by Brian Tee. Emily is described as a party girl and semi-professional gambler who “bankrolls her high-stakes betting by cozying up to rich men,” according to TVLine.

“Chicago Med,” which is on its third season, follows a fictional emergency department inside a medical center. Tee’s Ethan is an emergency room chief resident who served as a medical officer in the U.S. Navy.

Cho, who played Kira Yukimura on “Teen Wolf” for three seasons, left the show last year. She will also be seen next in the upcoming Zoe Saldana-executive produced film “Honored,” slated for a 2018 release.
