You can pour liquid nitrogen over your hand and it won't do much damage at all for a couple of seconds or so. It immediately evaporates and the gas forms an insulating layer. The problem is really when you're immersed in it. Say you're wearing gloves handling LN2 and some of it gets into your gloves ... then you're in trouble.
Not to mention that even a completely frozen hand wouldn't shatter like glass; the Mythbusters refuted that in a recent episode, albeit with skulls.
I wasn't enthralled by the mystery. I'm getting tired of the way they keep bouncing between suspects -- find a suspect, question them, clear them, find another suspect, question them, clear them, etc. It's very formulaic, as bad as
House's one-failed-diagnosis-after-another formula. I wish they'd do more episodes where the case develops differently, say, they can't find a suspect for a while, or they have more than one suspect that they can't easily clear, or just
something.
I was pleased to see Erin Cahill, who played the fiancee of the victim's brother. She was Jen on
Power Rangers Time Force, one of my all-time favorite Rangers (I put her fourth on my
Top Ten Female Rangers list). I didn't recognize her at first, though, since this show puts the credits so ridiculously late that I didn't see her name until after her first scene. I knew she looked familiar, but I figured it was just because she reminded me of Summer Glau. I never realized they resembled each other. Anyway, she's looking lovely.
Odd that at the end, Castle was the one favoring the "follow your heart" side of the discussion, but he was okay with helping Alexis make the opposite choice.
