I got a bit bored in the middle of this ep, to be honest.
The whole Greg thing moving around so nimbly when he was supposedly on the verge of death was annoying, as was the miraculous removal of both of them from the rubble (especially as I'm watching footage of the earthquake in Haiti this morning).
And next storyline is clearly going to Sarah being pregnant ...
I think the whole move towards a conspiracy theory has taken too long to get to.
(But I will still be glued to it next time!)
