Maybe it's because things are starting to lead to some sort of finale, but I actually felt this episode moved quite quickly and was surprised when the 54 minutes were up. Though there were effectively just two major settings (the house and CIA operations) this didn't stall the episode like in Rendition or The Middle Men, and I eagerly awaited each revelation as they were tantalisingly dangled.
Still, questions remain. Quite why the Torchwood tech liberated from the remains of the Hub is important remains elusive - as Jack said in the wrong hands it could destroy the timeline, but that actually explain why Angelo had it installed, or indeed why he happened to die just as Jack was there. For a while I thought it meant that Jack's kiss had the power to bring death in yet another twist, but that didn't seem likely as otherwise Brad back in Dead of Night wouldn't have been happy, protection or not! Did Jack short-circuit something? I have vague hopes it'll be properly explained later.
It was nice to see Angelo's story resolved too, and it wasn't a bitter twisted character after all, as the end of Immortal Sins implied - though Nana Visitor brought the embittered grand-daughter to life ... well until she was blown to bits of course, courtesy of Friedkin's allegiance to the Familues (bye bye Wayne Knight, another nice, brief celebrity role). The scene where Jack talks to Angelo about Ianto was touching, too, and didn't feel uncomfortably shoe-horned into the story (unlike the similar almost guilty mention in Dead of Night).

Speaking of which, how does someone who's apparently clever enough to set a trap for Friedkin then turn out to be Mr Thicko when it comes to accepting that nobody outside the null field generated by Jack can hear them talk, especially after witnessing all the tech that Torchwood has brought to bear throughout his time with them. I really can't understand how Rex got anywhere near his position in the CIA, maybe it is really is Esther who has helped his career progress.
Oh Esther, bright, astute (usually!) Esther, I do hope you survive through to the end of the series. Am I the only one who hopes that she ends up joining Jack on his adventures after this is all resolved? The 'intimate' moments between them (subtly suggested in The Categories of Life and in her caring about him tonight must be leading somewhere, surely?

And Jilly's been promoted and is off to Shanghai ... for some reason the image of Davros's offer to Tasembeker from Revelation of the Daleks came to mind at this point - do hope she knows what she's doing!
All-in-all, this was a much more enjoyable episode, which bodes well for the last 20% of the story - shame the preceeeding 70% of Miracle Day took so long to get here - the last thing we need is next week's The Gathering to stall yet again! Fingers crossed.
