I do think Bodie is a bit of a mysterious super-hero here, able to warm himself up like that. I'm half hoping he *will* teach this mental trick to Doyle at some point, so we can find out what it is! I'm also waiting eagerly to learn what turned Bodie from the guy Murphy remembered from six years ago into the Bodie we see now. And how he can survive without ever really sleeping. Doyle is much more of a normal human being with limitations, so far.
