I really like the way Lena is shown - she's not acting rationally, which is hardly surprising, some of her upbringing is coming through, and she's discovered she can't trust anyone, so has to rely on herself, but she doesn't have the experience to make sensible decisions at this stage.

I hadn't really thought about Daniel being willing to trust people, but that does explain some of his behaviour. Not a good characteristic for a spy though.

I enjoyed the episode, so much going on and wheels within wheels.
