Mac is very single minded in regards to the rescue of the sailors on the sub, which is an admirable trait, however... As I mentioned in the review for the first part of this two-parter, I do kind of wish that she might not get her way, that the crisis may not be resolved in the happy-happy way of tv land. There was a fair amount of tension through the show, and it was maintained very well, but just once it would be interesting to see how it would be treated if the real world were allowed to intrude.
The conversation that never happened between Mrs. Templeton and Jayne was an interesting touch - and of course, she goes back to work for him. Hmm... I hope this doesn't mean she becomes "the enemy" again, as I was just starting to like her as her own character separate from Nathan.
