One of the better finales RTD has done.
Was not expecting that ending with Jack and his grandson. Chilling.
Bridget : Made of win with those lenses. Though I was almost also expecting another gun... can't deny the PM deserved it.
Frobisher: Ouch. Ow ow ow. And made the worse by Jack saving the day eventually.
Dark, depressing, and totally in keeping with the series so far.
