Series 2, EP 17 (SPOILERS!!)

Hey everyone,

For those that have seen it, what did you think?
One of the best yet in my opinion!
So many questions... why did the prisoner not run away? Did he do something special to make the lights turn back on etc..? What are they going to do with him now they've found he's lying?
And what was the diagram in the main room (under UV light). Why the ration drop?

It can only get better from here, but I can't wait for ep 18!

The UV map was great - ton of speculation as to the other locations of the stations.

What did you think of Ep.18? I think they are really back on a roll.
