This episode does not let up its tension for a moment. It is an exhilarating ride, though I do think we missed opportunities for a couple more moments of silence.

BUT WHAT A RIDE. We get some gnarly special effects and twisted implications with Jack, we get some great moments for both Gwen and Ianto working independently of Torchwood, and new character Lois is excellent. Really really good

I forgot how little Captain Jack is in this episode, but you don't really miss him. Gwen has some really badass moments that more than make up for it, such as when she's taking down the ambulance drivers who are actually government spies, or breaking into the secret base where Jack is being held.

This has to be among Captain Jack's more gruesome deaths also. It's truly terrifying to think how much pain he must be feeling when you see his skin totally burnt, and he's just screaming.

Another excellent episode for sure.
