Viewers of “The Americans” know that it’s best not to get in Elizabeth Jennings' way or she may give you a trip to the dentist.
But in Wednesday's episode of the FX drama, it was Elizabeth (played by Keri Russell) who needed an appointment.
As if being a KGB spy wasn't fraught enough, Elizabeth has had some other matters to tend to this season. Her parenting views have been a point of contention with her husband Phillip [Matthew Rhys]; she's just become aware of her mother's failing health. And she's been insanely close to being captured by authorities -- leading to some toothache and an incredibly tense and intimate scene void of any anesthesia.
