This show is really starting to raise the bar. With Loyalty, I really started getting more Lost vibes, with a bit of 24 mixed in.
This episode focused on Simon and how events in his past shaped up to fit in with the present situation and molded the decisions we saw him make. The whole story with his girlfriend and how she recognizes him 40 years later, leading to their eventual conversation was very moving.
Meanwhile, Sean and Leila are finally finding out about the conspiracy and what Leilas father has to do with the "aliens", as the journalist called them (I still think they're time travellers). Can't wait to see exactly how the father ties in to everything.
The ending was a great cliffhanger, and the next episode previews looked great as well. Seems like the detainees still have a lot more to them than we think ;)
