S19E4: Red in Tooth and Claw. Jamie has some clever lines in this one, and Bernie the Badger was a cute little guy, loved the photos at the end. Dr. Kam has a well-acted substitute and his presence doesn't bode well for the future of Jamie's crush, poor guy. The guest actors (mostly) did a fine job as well. This episode was not the best in show, but an honorable mention at least.
