Sometimes when your friends act a little weird, you can chalk it up to a bad day, or maybe some bad news, or the rain. Or perhaps neural implants that keep her under the control of a psychiatrist working for a shadow organization looking to harness your laboratory's technology for evil. The latter happened on 'Eureka' (Mondays, 8PM on Syfy), when Jack suspected things weren't quite right with Allison.
Jack found out that Beverly, the psychiatrist in question, was the one responsible for his girlfriend's strange behavior. He locked her in a cell and asked what she'd done, but Beverly was clever and prepared, and with a click of her little keychain device, she sent the whole town into a temporary coma.
