The second episode builds nicely on the first by involving the characters more and more in their dilemma. What I particularly liked about it are the human reactions to what's going on; no JOHN WICK style faceless killing here, rather a very real and considered response to an impossible situation, with all the frailty and weakness that we as mankind face on a daily basis. It has depth, quality acting, lots of suspense and a wonderfully sick joke at the climax which I didn't see coming.
