It's kind of amazing that Luke looks more cleanly groomed after being in a prison for three months than he usually looks when he supposedly has access to hot running water and razors every day. Funny that. The goatee was well trimmed, no five o'clock shadow, hands were well-manicured, and looks like he'd recently had a hair cut.
Those Casadines must run a five star prison.
ETA: Nevermind. I was missing several minutes of the recording, the entire scene between Helena and Luke. A kind soul just emailed them to me since, as she said, one musn't ever miss awesome Helena scenes.
