This one was fairly effective. I think the characters are starting to gel more, and we're getting to explore some interesting variations on their dynamics. It was intriguing to see Snart acting as a conscience for Sara, rather the reverse of what you'd expect. And Mick showed some humanity in response to Ray's self-sacrifice on his behalf -- it's nice to see he has more than one dimension after all. (I also noticed that his arms were made up to look scarred from burns. I guess that fits the character.) But it remains consistently evident that Rip Hunter is a really, really bad team leader. Things only went right here because they ignored Rip's plan.
And yes, I caught the in-joke where Wentworth Miller said "This isn't my first prison break." Although I never actually watched that show.
I wonder -- is Valentina dead, or will she return as Negative Woman?
So... Savage has been caught in a conventional explosion and then, moments later, a nuclear explosion (or at least been very near it). I imagine it'll take him a fair amount of time to heal from that.
