A lethal killer has infiltrated The Flash‘s S.T.A.R. Labs, and we’re not talking about Dr. Wells — but this one is after the sketchy scientist.

In TVLine’s exclusive video from tonight’s episode (The CW, 8/7c), Walking Dead alum Emily Kinney’s Brie Larvin aka Bug-Eyed Bandit has let loose a robotic bee in S.T.A.R. Labs, and it’s hungry for honey blood.

Cisco and Caitlin are able to escape the pest’s deadly wrath, but Wells is not so lucky and requires a (somewhat begrudging) assist.

Press PLAY above to see who saves the doc’s life and to get a first look at Kinney’s chillin’ villainess.
